-->-- '''[[Franchise/IndianaJones Indiana Jones]]''', ''[[Film/RaidersoftheLostArk Raiders of the Lost Ark]]''

The favorite plan (or rather, lack thereof) of almost every ActionHero and IdiotHero in existence.

The Indy Ploy is when someone improvises a plan in the middle of the action, or comes up with one immediately before the action starts. Either way, the initial plan has failed, and now the character is forced to come up with a new plan on the fly with no time to prepare or think about the consequences. Maybe TheTeam has lost TheSmartGuy. Maybe TheLeader has the attention span of [[AttentionDeficitOOHSHINY a distracted goldfish on caffeine]]. Maybe ThePlan our heroes were relying on was [[LeeroyJenkins trashed beyond all hope of being salvaged]]. No matter the reason, they are now executing an Indy Ploy.

Not all characters involved are necessarily aware of the leader's lack of forethought. When he finally utters those dreaded words, "I'm making it up as I go", [[HilarityEnsues hilarity is sure to ensue]]. If things don't go smoothly, expect exclamations of "WhatWereYouThinking!"

An Indy Ploy is also a surefire way to invoke an UnspokenPlanGuarantee. Since Indy's course of action is unknown even to Indy himself, and therefore unknown to the audience, Indy is ''more'' likely to succeed than if he had spent time planning on-screen.

Named after Franchise/IndianaJones, who has had to make more hasty exits than most of us have had hot dinners.

Contrast StrategySchmategy (where the character just acts at random without even improvising a plan on the fly), XanatosGambit (a plan where all reasonable outcomes are beneficial) and BatmanGambit (where the gambitter uses his knowledge of what all involved will do in order to use them as pieces on the board). Between them and this trope lies XanatosSpeedChess, where the plan, generally more complicated than "survive and don't get caught", is continually adapted to circumstances. This can lead to a SpannerInTheWorks where they cannot be predicted ''because'' they don't know what they are going to do next.

[[folder:{{Anime}} and {{Manga}}]]
* In ''Anime/MazingerZ'', [[TheHero Kouji]] is able to think strategically and plot strategies beforehand. However, given his rash, hotheaded nature, he is VERY prone to impulsively rush/leap/dive headfirst into a dangerous situation and figure out along the way how he will walk out of it alive. These [[http://www.mangago.com/r/l_manga/manga/mazinger_z_relic_of_terror/mf/manga/mazinger_z_relic_of_terror/c000/26/ two]] [[http://www.mangago.com/r/l_manga/manga/mazinger_z_relic_of_terror/mf/manga/mazinger_z_relic_of_terror/c000/27/ pages]] of the "Mazinger Z: Relic of Terror" one-shot are a good example.
* In ''Manga/{{Naruto}}'', Deidara prides himself with these, as it correlates with his belief that true art is a momentary concept.
** Naruto himself has twice been described to mooks who had never seen him before as "[[LeeroyJenkins the one who will attack you without thinking first]]". While he can often make up plans (even very good ones), he initially is only capable of thinking them up immediately before he has to do them. Of course, this is somewhat implied to be why he's a capable fighter; he makes up for his lack of raw intelligence with body instinct.
*** It actually works in his favor. Considering that literally everyone he's fought has pulled new and unheard-of secret techniques out of their ass when he fights them, trying to plan ahead would be a pointless exercise. What little strategy he had (at least until recent chapters) has been "spam them with [[MesACrowd Shadow]] [[ZergRush Clones]] until they break out the big guns, and then figure it out from there." ''The kid plans for Indy Ploys.''
* Luffy of ''OnePiece'' did this once or twice. At one point the main characters were making a minutely-detailed plan to invade a government-owned island. Luffy, being the IdiotHero that he is, [[LeeroyJenkins charged in at the soonest possible moment]], leaving his allies to beat a hasty path in after him. Not that it really mattered. They used the same plan to get the rest of the Straw Hats in and it worked. Luffy just got in early and defeated the first [=CP9=] member.
** His fight with Eneru may also qualify. With his "Mantra" Eneru was able to predict and counter all of Luffy's moves, so he just started making up moves on the spot in an effort to get around it.
** Two particularly interesting tactics of his; first, to allow himself to go into a daze and let instinct keep him from getting hit (didn't work because he couldn't attack without breaking the trance) and throwing his fists against the wall (they're made of rubber) to let them ricochet unpredictably.
** When Luffy ''does'' have a plan, it usually amounts to "let's beat up the bad guy!" Anything else, he makes up as he goes (or has to be planned by a subordinate, usually Robin or Nami, or occasionally Usopp.)
* In the manga ''Manga/BattleRoyale'', Shuuya has an admirable tendency to jump into a conflict to help the underdog. The problem is that he never thinks about what he'll do after he becomes part of it. He usually reveals his Indy Ploy after the conflict is already resolved and the other person asks what he was thinking.
** And a lot of the time it turns out his plan was no more elaborate than 'jump in and hope for the best.'
* Use of the Indy Ploy is the totality of the Saotome School of Martial Art in ''Manga/RanmaOneHalf''.
** With one exception. When Ryouga learns the breaking point technique, Ranma employs the secret Saotome technique of... running away from the fight to think of a plan.
* Nearly ''every'' victory in ''Anime/TengenToppaGurrenLagann'' is like this. The one time the protagonists plan before a fight, they win, but [[spoiler:Kamina dies in the ensuing victory.]]
** And it's not like any plan they make will have more than 1% chance of success. [[spoiler:As they can pull off even something with [[CrowningMomentOfAwesome 0 chance]] of success, it doesn't really matter...]]
* In ''Manga/{{Eyeshield 21}}'' this will happen quite often with the Devil Bats, especially near the end of the series. It is particularly prevalent on the last kick returns and when the Japanese team uses the [[spoiler:Dragonfly and Golden Dragonfly]]
* ''Manga/PokemonSpecial'' makes thorough use of the Indy Ploy - Gold in particular worships at its altar. His are so blatant that mental objections fill the panel when he acts like he planned it all along. It's hard to judge, given the nature of her intellect, whether some of Sapphire's more clever victories (Roxanne, Brawly, Ark @ Mt. Chimney) qualify as this or something between this and XanatosSpeedChess.
* ''Manga/InuYasha'': This pretty much exemplifies Inuyasha's entire approach to fighting. He even learns Bakuryuuha totally without meaning to by reacting instinctively. His unconventional fighting style is commented on by other characters on more than one occasion.
* As a leader, this is both Ichigo of ''[[Manga/{{Bleach}} Bleach's]]'' strength and weakness. On one hand, he can be so aggressive, and attempt such suicidal things with such limited preparation, that it astonishes and repeatedly catches more cautious foes off-guard. On the other hand, when the villains DO know what to expect from him, his impetuosity and lack of foresight makes him a real UnwittingPawn.
** Renji has shown shades of this on occasion with varying degrees of success.
** In his fight with [[spoiler:Shukuro Tsukishima]] Byakuya of all people was forced to do this as his opponent's ability [[spoiler:allowed him to "insert" himself in someone's past, and he used it to learn any move Byakuya ever trained]], so Byakuya had to improvise something unexpected. Later he admitted he enjoyed it.
* ''Franchise/LupinIII'' uses UnspokenPlanGuarantee so often that we, the audience, can't tell if Lupin's success is due to planning or luck.
** In "The First Move Wins Computer Operation!" of the original 1971 ''Anime/LupinIIIGreenJacket'' TV series, the Tokyo police department gets a supercomputer that is programmed to predict Lupin's every move. It does so extremely successfully, until Lupin realizes the way to beat it, is to throw out all his plans and act completely on whim.
** This plot was revisited in the ''Anime/LupinIIIRedJacket'' series, where an armchair detective (criminologist) programmed a computer to do the same thing. This time, Lupin's IndyPloy was to rely on Zenigata's whim.
* Joseph Joestar, the second titular hero of ''Manga/JoJosBizarreAdventure'', is a seasoned practitioner of these, both as a young practitioner of Ripple-style martial arts and as an [[OlderAndWiser Older and kinda-sorta Wiser]] mentor to his grandson Jotaro. Fittingly, his characterization in Part 3 draws heavily from the TropeNamer, right down to the CoolHat.
* In ''Anime/IrresponsibleCaptainTylor'', the titular character lives his life by this philosophy. Or he's a super genius that plans everything far in advance. [[AlternativeCharacterInterpretation It's hard to tell]].
** In one episode, this was discussed when Tylor has a debate with Yamamoto about what happens if all plans against the enemy fails. Tylor's point was that sometimes all plans can fail and you must think fast at that point to win. Yamamoto dismisses Tylor as being an idiot, only to look in shock later in the episode, as Tylor's attempt to escape the Raalgon fleet pursing them - after all before plans failed - resulted in the whole Raalgon fleet getting wiped out by their own actions. Leaving the crew wondering, if Tylor was just lucky, or used an Indy Ploy against the Raalgon Fleet.
* Yusuke Urameshi in ''Manga/YuYuHakusho'' uses random tactics in an effort to win, most notably during his fight with Hiei which, afterwards, Botan notes he "risked their lives on a maybe" as well as Yusuke's first fight against Sensui where he attempts to counter Sensui's ability to predict moves by doing things that are entirely random (such as going for a swim mid-battle).
** "Come on Genkai, this is me we're talking about, I'm just making it up as I go!"
** "Alright Yusuke, you're out of options, time to do something stupid!"
* Goku from ''Franchise/DragonBall'', especially during his assault on the main Red Ribbon Army base. His plan could be best described as "keep hitting anyone who attacks until you run out of targets". Meanwhile the rest of the cast were busily trying to put together a rescue team and trying to plan out how they'd save him.
* Judau Ashta from ''Anime/MobileSuitGundamZZ'' and Uso Ebbing from ''Anime/MobileSuitVictoryGundam'' are masters of this. They make up new plans as they go along, using strategies more experienced or more crazy pilots never think of. Before them, Kou Uraki of ''Anime/MobileSuitGundam0083'' turns out to be incredible at this, with his crowning moment being the rather insane plan that he enacts to take out the Gundam GP-02A.
* The ''entire'' Tekkadan crews from ''Anime/MobileSuitGundamIronBloodedOrphans'' are experts of solving problems via improvisation, from wiring a meteor to reposition the ship, to landing mobile workers onto enemy ship via ramming on it.
* ''Manga/OuranHighSchoolHostClub'': Tamaki is surprisingly good at them. Like, trump [[TheChessmaster Kyoya]] good.
* ''Anime/CowboyBebop'': Spike "I try not to think" Spiegel is a contrast to Jet, especially {{Lampshaded}} over a game of TabletopGame/{{Shogi}} in [[BigDamnMovie the movie]]. When he does make plans, they're simple and disposable; he expects them to fail, leaving him no choice but to improvise.
** To quote the manga: "Plan A is 'Take it as it comes,' Plan B is 'First come, first served,' and Plan C is 'Wing it.'"
* Having a strong preference for the Indy Ploy seems to be a requirement to be a member of ''Manga/FairyTail''. Even many of the more sane characters tend to throw themselves into fights with little forethought (Erza fits this description well), notable exceptions may be Lucy, Levy, and Fried.
* Judai from ''Anime/YuGiOhGX'' builds his reputation so much on this that [[TheAce Kaiser Ryou]] becomes disappointed when the former tries dueling more strategically against him in the latter's graduation duel. He brings himself back from the brink by going to his old (non-)strategy and ends the duel in the draw.

[[folder:Comic Books]]
* This is generally the M.O. of just about every comic book superhero, since supervillains have a tendency to attack without warning at any time. But while most of them do at least fight according to plans thought out in training or, on the rare occasion, when they're the ones tracking a bad guy instead of the other way around, Franchise/TheAvengers change their line-up so frequently that they can't even plan for their own team, let alone whatever they're up against. Winging it is what they do best.
* In an issue of Green Lantern Sinestro cites this as the key reason he can never beat Hal Jordan (as much as he hates to admit it):
-->'''Sinestro''': You're too blasted unpredictable. Set a plotter or a schemer in my path, I'll crush their bones to dust. You've escaped that fate not because of something as silly as willpower. Nor because of your prosaic notions of justice and morality. You've survived because your actions never make sense. Yet despite yourself—-and this is the truly infuriating part—-your instincts always see you through.
* In the old Snarfquest comic that ran in ''Magazine/{{Dragon}}'' Magazine, Larry Elmore plotted out the next step and place for the characters to be, then threw it out and literally made up the craziest possible way to get there from the last stopping place. Best Example: ''"You Shot My Tower!!"'' Snarf DID.
* Franchise/{{Batman}}, despite his reputation for [[CrazyPrepared intense planning]], actually owes most of his victories for [[AwesomeByAnalysis noticing every detail of his situation]] and then making a plan to take advantage of it on the spot.
* Hawk, of the duo Hawk and Dove, reportedly has unpredictability as a super power. Despite some rather basic tactics (find the toughest guy in a group and attack him head-on), all mystical and mundane attempts to predict his actions automatically fail.
* Crazy comic book AntiHero {{Deadpool}} has twice bested Taskmaster, a character capable of beating some of the very best superheroes (the low-to-mid-level ones, anyway -- little chance of him taking down Thor or Ms. Marvel, for example, except by planning) by being able to [[AwesomenessByAnalysis perfectly mimic and therefore predict]] their fighting styles. The reason he was defeated by Deadpool, it is revealed, is that Deadpool, being [[AxCrazy almost as crazy as The Joker]], literally makes up everything he does as he goes along, making him completely unpredictable.
** The instance where he took Taskmaster off guard by suddenly stopping in the middle of their fight and going into a breakdancing routine is a sterling example of [[CrazyAwesome Deadpool's M.O]].
** This was also used in the DC Universe, when [[ComicBook/{{Batgirl 2000}} Batgirl's]] (Cassandra Cain) body language reading skills were foiled by the Joker's randomness. Cassandra triumphs after Oracle explains that the Joker's body language is "gibberish".
*** Which makes sense in that the only consistency in the last five or six iterations of the DC universe is that Joker literally makes up his personality as he goes along.
** The miniseries ''Dream War'', a CrisisCrossover between the Creator/{{Wildstorm}} Comics and Creator/DCComics universes: In a conflict with DC villains, Midnighter of the Authority usually had an advantage, due to his ability to play out every variation of a fight in his head before the first blow lands. Until he ran into the Joker and could do nothing but stand completely still because he couldn't figure out what the Joker would do.
* Parodied in the ''Republic'' series of ''Franchise/StarWarsExpandedUniverse'' comics, where [[LoveableRogue scoundrel]] Vilmarh Grahrk paraphrases Indy: [[http://www.darkhorse.com/reviews/previews.php?theid=10-455&p=1 "I don't know! Am making this up as I go!"]]
** This probably counts as an [[Creator/HarrisonFord Actor]] [[ActorAllusion Allusion]] as well.
* Like in the ''Shanghai Noon'' example below, in ''ComicBook/{{Asterix}} and the Cauldron'', after Obelix doesn't understand a detailed plan, Asterix replaces it with "we fight, get the gold and go away" (to which Obelix replies "This one I understand!").
* Franchise/SpiderMan does this every now and again, often against enemies that outclass him in terms of power. One notable instance involved him defeating Nitro (yes, [[ComicBook/CivilWar that Nitro]]) by luring him into a chemical warehouse full of tear gas and webbing a tank of it to Nitro's body. When Nitro exploded, he vaporized the tear gas, which then mixed with his gaseous form and left him too sick to stand up, much less explode again, when he reformed. It's even {{Lampshaded}} by Spider-Man when he realized he had all of five seconds to stop Nitro before the villain exploded again.
* Reed Richards of the ''ComicBook/FantasticFour'' can afford to use this as his modus operandi, since he's smart enough to pull a master plan that would take anyone else days to draw up out of his ass at random, or cobble together an interdimensional continuity de-snarler out of a handful of kitchen utensils.
* Similarly, his sometime-colleague Comicbook/DoctorStrange frequently goes to cases without much preparation, expecting that he'll be quick-witted enough (or have the right amulet, or know the right spell) to deal with the situation as it develops.
* ''ComicBook/DungeonsAndDragons'' Despite being the group's Fighter, this is basically Adric's primary skill for the series. The rest of the group is fully aware that he effectively makes his plans up as he goes, but they're actually all okay with that.
-->Khal: "Adric's plans are rarely ''good'' ones, but they're quick."
-->Varis: "You'd be surprised how much more useful a skill that is in the adventuring trade."
* In comparison to [[ComicBook/CaptainAmerica Steve Rogers]]' CrazyPrepared-ness, ComicBook/BuckyBarnes, after assuming the mantle of Captain America showed off his tactical sensibilities through his extensive reliance on plans made on the fly.
* ComicBook/NikolaiDante is shown to pull this off all the time. [[UpperClassTwit Flintlock]] reckons that his tactics involve hurling himself in front of increasing numbers of enemy guns.
* Usually ComicBook/{{Diabolik}} relies on careful planning and being so CrazyPrepared and ProperlyParanoid to make ''Batman'' seem unprepared. Yet, once in a while even ''he'' gets caught with his pants down, and has to improvise. But if you're in his way you're better pray he ''did'' plan for whatever you have, because his Indy Ploys tend to involve more murder than usual-and this is a guy whose escape plan once involved ''luring the police in an area that automatically filled with DeadlyGas''.
* An InformedAbility of Jazz from ''ComicBook/TheTransformers,'' intended as a contrast to Prowl as the Autobot's StrawVulcan. Where Prowl is obsessed with planning and order, Jazz is creative and improvisational. In fairness, when they ''do'' get to show off these tendencies, they work about as often as not.

* In the ''WesternAnimation/JackieChanAdventures'' fic ''Fanfic/QueenOfAllOni'', when Jade has to capture Tohru for Ikazuki, he stays under the shop's wards during the attack, preventing her or her forces from getting close enough to grab him, she has one of her ninjas attack Uncle, KNOWING Tohru will charge to his sensei's rescue, and captures him. And keep in mind, she comes up with that plan ON THE SPOT!
* ''FanFic/ShinjiAndWarhammer40K'': How [[GodEmperor God-Emperor]] [[MindScrew Shinji Ikari]] handles combat with the Angels. On at least two occasions he successfully stabs them with their own ripped-out teeth.
* The ''Series/{{Firefly}}'' fanfic ''Fanfic/{{Forward}}'' continues the original series' fine tradition of Mal making it up as he goes. In the "Condor" story arc, it gets {{Lampshaded}} by Zoe, who is relieved when Mal says their harrowing escape is being made up on the spot, and in the "Third Interlude" chapter, Jayne pulls an Indiana Jones-style vehicle boarding where he's improvising as he goes.
* Plenty of these in ''Fanfic/WithStringsAttached''; indeed, the second half of the Fourth Movement is ''made'' of these.
* [[Fanfic/ScarsSamsara Scar's Samsara]] has Scar smooth-talk an army of hyenas which are about to eat him into attacking Pride Rock, thinking that he'll have thought of a plan to make use of the distraction by the time they arrive.
* ''Fanfic/TheKeysStandAlone: The Soft World'' has a bunch of these as well. For example, John uses a literally last-second ploy to get himself and Ringo out of the clutches of a roomful of [[MoreThanMindControl telepaths and empaths busily trying to bend them to their will]].
* Takato from the ''FanFic/TamersForeverSeries'' is ''exceptionally'' good at this, to the point where it crosses the line into XanatosSpeedChess territory.
* ''FanFic/NotQuiteAsPlanned'': Ichigo has this to say after him and the gang escape from Gin and two Espada:
--> "That's it! We are never planning things again! Not when the things we make up on the fly works 10 times better."
* In ''Fanfic/TheWitchOfTheEverfree'', while she eventually grows out of it, Sunset Shimmer starts out thinking this way, although she isn't nearly as effective at it as she thinks she is, and eventually starts making actual plans.
-->I didn’t need to plan. I was Sunset Shimmer, the strongest unicorn in Equestria. Planning was for ponies who didn’t have the strength to just do what they wanted. I could do '''anything'''.
* Zigzagged in ''Fanfic/YuGiOhTheThousandYearDoor'', where Kyle does indeed have a plan to get him and Drake out of the MortonsFork situation they're in [[note]]They are opponents in the final round of the semi-finals of a tournament which is clearly NotJustATournament; the losers life will be in danger, while the winner will end up an UnwittingPawn of the BigBad during the quarterfinals.[[/note]] but...
-->'''Drake:''' This better be a good plan, Kyle.
-->'''Kyle:''' Actually, it's a ''stupid'' plan. As in, the type you try when you're desperate, and people tell you 'it would never work', but it's the only thing you can think of because you're in a pretty bad situation?
-->'''Drake:''' Like the kind we're in now?
-->'''Kyle:''' Exactly

[[folder:Films -- Animated]]
* [[Franchise/DisneyAnimatedCanon Disney's]] ''Disney/{{Aladdin}}'':
--> '''Genie:''' Al, I can't help you, I work for Señor Psychopath now. What are you gonna do?\\
'''Aladdin:''' Hey, I'm a [[StreetUrchin street rat]], remember? I'll improvise.
* ''WesternAnimation/TheIncredibles'':
** Though not an IdiotHero, Helen is able to do this very well. It helps that besides being the mother that needs to balance, control, and maintain her family, she can adjust herself in various ways to accommodate her own plans.
** Bob is a straighter example of this. His own experiences as a hero aside, working with and being married to Helen probably contributed a lot to his ability to think fast and adapt to situations quickly.
* Disney is quite fond of these, appearing again in ''Disney/{{Mulan}}''.
-->'''Mushu:''' So what's the plan?\\
'''Mulan:''' Um...\\
'''Mushu:''' You don't have a plan?!\\
'''Mulan:''' Hey, I'm making this up as I... [[EurekaMoment go]].
* From ''Disney/TheHunchbackOfNotreDame'', during Quasimodo's helping Esmeralda escape the cathedral via rooftop;
-->'''Esmeralda:''' Have you ever done this before?
-->'''Quasimodo:''' No.
* ''WesternAnimation/{{Megamind}}'': Ironically one of the ''only'' plans of Megamind's that works is basically one of these:
-->'''Roxanne:''' What's the plan?
-->'''Megamind:''' Well, it mostly involves ''[[TryNotToDie not dying]]''.
-->'''Roxanne:''' I ''like'' that plan!
* ''WesternAnimation/KungFuPanda2'', when Po rescues the Furious Five from Lord Shen:
-->'''Tigress:''' What's your plan?\\
'''Po:''' Step 1, free the Five.\\
'''Viper:''' What's Step 2?\\
'''Po:''' To be honest, I didn't think I'd get this far.

[[folder:Films -- Live-Action]]
* Franchise/IndianaJones, as played by Creator/HarrisonFord, is the TropeNamer. On his myriad of adventures, Dr. Jones has rarely, if ever, planned things out in advance, but always manages to either escape death or come out on top. He's called the "Patron Saint of {{Player Character}}s" for a reason. Examples include:
** At one point in ''Film/IndianaJonesAndTheKingdomOfTheCrystalSkull'' it doesn't work, where Indy tries to jump onto a truck and misses.
--->'''Indy:''' Damn, I thought that was closer.
** {{Lampshaded}} later in the film:
--->'''Mutt Williams''': What's he gonna do now?\\
'''Marion Ravenwood''': I don't think he plans that far ahead.
** And then he pokes his head between them with a ''[[http://en.wikipedia.org/wiki/RPG-7 RPG-7!!!]]''
--->'''Indy:''' Scooch over, will you, Son?\\
'''Mutt''': (eyes wide) Don't call me, "Son!"\\
'''Indy:''' (''completely'' ignoring Mutt) I'd cover my ears if I were you!\\
(Cue StuffBlowingUp. ''Giant saw blade comes flying at them.'')\\
'''Indy:''' Duck! Duck!
** Hereditary. Witness Indy's dad in ''Last Crusade''. "I suddenly remembered my Charlemagne."
*** In the same movie, Sallah asks "What are we going to do now?" to which Indy responds, "I don't know, I'm making this up as I go."
** In-universe, Indy seems to have picked up the "making this up as I go" line almost word for word from a group of older gentlemen while on a special mission during WWI (''Series/TheAdventuresOfYoungIndianaJones'', Phantom Train of Doom).
--->'''Old Soldier:''' Youngsters and their plans...
--->'''Young Indy:''' What's wrong with plans?
--->'''Captain Selous:''' Nothing. As long as you're willing to adapt when they don't work out.
--->'''Young Indy:''' Make it up as you go? [[SarcasmMode That'll work...]]
** He even does this as a ''teenager'' - in ''Film/IndianaJonesAndTheLastCrusade'', when fellow scout Herman asks how he's going to get the Cross of Coronado away from Fedora and his men, he admits that he doesn't know, but he'll think of something.
** In ''Kingdom of the Crystal Skull'', Mac, who knows Indy, immediately assumes playing chicken with vehicles is a really bad idea, because Indy's going to pull something unexpected -- in this case, it turns out, pulling himself up and out of the car at the last moment and letting the crash happen.
** Probably his ballsiest (if not outright insane) ploy was in the climax of ''Film/IndianaJonesAndTheTempleOfDoom''. Indy is in the middle of a rope bridge, surrounded on both sides by Thugees. Mola Ram forces Willie and Short Round to go out onto the bridge with him. Indy quickly wraps his leg around a rope railing and yells something in Chinese to Shorty, who quickly wraps his arm likewise and tells Willie:
--->'''Short Round:''' Hang on lady, we going for a ride!
--->(''Willie sees Indy raising his sword and realizes what he's going to do'')
--->'''Willie:''' OH MY GOD. Oh my god! Oh my god! (''wraps rope around arm'') Oh my god! Is he nuts?!
--->'''Short Round:''' He no nuts. He ''crazy!''
--->'''Indy:''' Mola Ram! Prepare to meet Kali! IN HELL!
--->(''Indy cuts the rope bridge with his sword and the bridge splits in half, sending the Thugees into the river below.'')
* ''Franchise/StarWars''
** Qui-Gon Jinn: "We don't have time for a plan."
** Both the rescue/escape from the original Death Star and the attack on the second (the Battle of Endor) amount to extended improvisation, as our heroes' plans run into the unexpected again and again.
*** In the NPR Radio Drama of A New Hope, Luke is actually commended by a Rebel leader when he admits that rescuing Leia from the Death Star was improvised, because "the ability to think on one's feet isn't common."
** Imperial fleet on your tail and the hyperdrive isn't working? [[TryAndFollow Fly directly into a nearby asteroid field.]] Later, when the fleet is back on your tail and the hyperdrive ''still'' isn't working? Turn around, make like you're going to ram the Star Destroyer's bridge tower... and instead, latch onto the back of it and power down (so you can detach and drift away later while no one's looking).
** Han gets back into it in ''Film/TheForceAwakens'', coming up with ad-libbed plans, usually reliant on doing things with a hyperdrive nobody has yet been stupid enough to try. Some of them even work.
--->'''Rey:''' Is that possible?\\
'''Han:''' I never ask that question until after I've done it. [==]
** Amusingly enough, he is less than impressed when Finn reveals that his plan [[spoiler:to infiltrate Starkiller base, disable its shields and rescue Rey]] is just one of these.
--->'''Han:''' People are counting on us. The ''galaxy'' is counting on us!\\
'''Finn:''' Solo, we'll figure it out. ''[brightly]'' We'll use the Force!\\
'''Han:''' ''That's not how the Force works!''
* ''Film/TenThingsIHateAboutYou'': To get Patrick Verona [Heath Ledger] out of detention after his big romantic gesture by way of apology for an earlier thing, Kat Stratford [Julia Stiles] improvises a distraction for the soccer coach running the class. The plan? Draw his eye by talking about a BaitAndSwitch ploy... and when all else fails, [[spoiler:flash him.]]
--> '''Kat:''' Ok... now that you've seen... the plan, I gotta go... and... show the plan... to someone else. ''(leaves with LuminescentBlush)''
* ''Film/SchindlersList'': Oskar Schindler's munitions factory doesn't produce a single shell during the war, all while Schindler keeps coming up with excuses to give to the Germans. Throughout the entire film (including the introductory sequence which highlights what a huckster Oskar really is), he's relying solely on his natural charisma, bribes, and pure guesswork. Creator/RogerEbert's own review of the film said it best:
-->''"Schindler outsmarted it, in his own little corner of the war, but he seems to have had no plan... We know that [[IKnowYouKnowIKnow Stern understands this]]. But there is no moment when Schindler and Stern bluntly state what is happening, perhaps because to say certain things aloud could result in death."''
* In ''Film/TheFugitive''. A character even notes this: that he's too smart for even the FBI to catch him, even though he's never been a criminal on the run before.
* There was a 90's movie, ''Film/PresumedInnocent'' which had an "Indy plot" bordering on an IdiotPlot where the whole plot goes random and every character has to make shit up off the top of his/her head at the moment. All the best laid plans turn the plotters into [[UnwittingPawn Unwitting Pawns]]. [[spoiler:The wife was the murderer, and she just wanted to get her husband's attention, who would cover it up. When he got on trial, she wanted to confess, but there was no evidence against him. He's struggling the whole movie to get the evidence, only for it to be right in front of his nose, in the desk of a cop friend of his. And the whammer? The judge was at the end of a ParanoiaFuel not-at-all-subtle attempt at blackmail ''by the defense attorney'', judge who despite all odds stoically refused to succumb to it. The accused only escaped not because he was innocent, but because ''he seemed innocent'' because there was no evidence. [[ArsonMurderAndJaywalking Oh yeah]], and there was [[RedHerring no conspiracy]] to frame him, as stated above, on the contrary.]]
* ''Film/MadMaxBeyondThunderdome''
-->'''Max:''' So what's the plan?
-->'''Pig Killer:''' ''(laughing)'' Plan? There ain't no ''plan''!
* ''Franchise/PiratesOfTheCaribbean''
** It is hard to determine whether Jack Sparrow [[ThePlan plans it all out beforehand]], or just makes it up as he goes along (it was [[LampshadeHanging lampshaded]] at one point in the third movie). That's a part of what makes him the LovableRogue he is.
** Subverted in ''Film/PiratesOfTheCaribbeanOnStrangerTides'', Jack drops a napkin minutes before using it as his exit strategy, making one wonder just how Indy Ploy he really is.
** Will Turner's "plan" in ''Film/PiratesOfTheCaribbeanDeadMansChest'' is basically to go over to the wreck and see what he can find. His strategy if anything happens: improvise. (Which, naturally, he does.)
* ''Film/DieHard'': John [=McClane=] is also prone to this. Bungee-jumping with a fire hose, [[EyeScream killing someone with an icicle]], jumping on a subway train from a sidewalk hole, [[CarFu throwing cars into helicopters]] ("I was out of bullets")...
--> '''John:''' I know what I'm doing.\\
'''Zeus:''' [[BlasphemousBoast Not even God knows what you're doing!]]
* Parodied in the original ''Film/ShanghaiNoon'', where Owen Wilson's character - at this point a train robber - comes up with an elaborate and well-timed plan to stop the train and get the money seamlessly. His men - who [[{{Mook}} aren't the brightest of the bunch]] - stare blankly and Owen reluctantly agrees to "wing it."
* In ''Film/OceansTwelve'', half the crew is jailed and the remaining half tries an Indy Ploy to achieve the mission, including having [[spoiler:Julia Roberts try to pretend she's Julia Roberts]]. The plot fails, but anyway [[spoiler:everything was a GambitRoulette from the beginning.]]
* In ''Film/{{Ghostbusters 1984}}'', this ploy fails spectacularly the first time the not-yet-heroes attempt it.
-->'''Venkman:''' "'Get her!' That was your whole plan, 'get her.'" ''[laughs bemusedly]'' It was scientific.
-->'''Stantz:''' I just got over-excited!
* ''Film/DownPeriscope''. Almost everything Lt. Cmdr. Dodge does amounts to winging it. Given the conditions of the exercise, an old diesel sub versus much of the US Navy's east coast fleet, it's also the only way to succeed.
-->'''Dodge:''' Men, we'll need to use a tactic that is somewhat bizarre and extremely risky.
-->'''Spots:''' Actually, sir, I think we prefer to go with bizarre and risky. It's worked for us so far.
-->'''Stepanek:''' I think we should continue to kick ass, sir.
* ''Film/PunisherWarZone''
-->'''Paul:''' So what's the plan?
-->'''Frank:''' I'm going to go in and get them.
-->'''Paul:''' You call that a plan?!
-->'''Frank:''' It's all I ever need.
* Marty [=McFly=] and Doc Brown have to make up things on the spot frequently in the ''Franchise/BackToTheFuture'' series, especially when unexpected things come up to nearly screw Doc's elaborate plans.
* Before heading into the final shootout in ''Film/TheWayOfTheGun'', Parker and Longbaugh agree that "a plan is just a list of things that don't happen."
* ''Film/TheDarkKnight'': Joker claims to be doing this, but it's really really unlikely most of the time, considering the fact that he knew exactly how everyone in the city would react [[spoiler:right up until the grand finale]], with Batman himself being the only wild card, and a minor one at that. Considering how well everything worked out, it's more likely he's falling back on the character's long standing similarity to Batman, doing what he can to plan ahead and making up what he can't. It's also possible that he's playing it up to inspire fear. After all, the only thing more frightening than a psycho with a plan is a psycho without a plan ''who manages to succeed anyway''.
* Witness this exchange from the 2009 ''Film/StarTrek'' movie:
-->'''Chekov''': If Nero's ship detects us he will destroy us. But, if we drop out of warp near one of Saturn's moons... say... Titan. The magnetic distortion from Saturn's rings will shield us. (Note: at this point, Mr. Scott's weird beaming technology will enable them to beam from the Enterprise all the way to Nero's ship at Earth)
-->'''Mr. Scott''': Aye... that ''might'' work.
** Earlier than that, after Kirk becomes the captain of the ''Enterprise'':
-->'''Uhura:''' I sure hope you know what you're doing, ''Captain''.
-->'''Kirk:''' So do I...
* Pretty much all of ''Film/{{Inception}}'' involves this, with Cobb's team forced to improvise as they go. Cobb himself even says that once they enter Fisher's mind, they'll have no idea what to expect, so they have to improvise as they go deeper into his subconscious. In fact, the entire "Mister Charles" gambit is one of these that the team cooks up when they realize they're going to be mobbed by armies of Fisher's personal security guards.
* ''Film/ThreeAmigos!''. The title characters do this because they aren't very bright.
-->'''Dusty:''' We have a plan.
-->'''Carmen:''' What is it?
-->'''Dusty:''' First, we break into El Guapo's fortress.
-->'''Carmen:''' And that you've done. Now what?
-->'''Dusty:''' Well, we really didn't expect the first part of the plan to work, so we have no further plan. Sometimes you can overplan these things.
* In ''Film/{{Stripes}}'' John has gotten them into the Soviet camp in Czechoslovakia. When asked what now, he says "Working on it."
* Sam Flynn in ''Film/TronLegacy'' gives us this exchange:
--> '''Kevin Flynn:''' Wait, what's your plan?\\
'''Sam Flynn:''' I'm a User. I'll improvise.
** Sam probably gets this from his father, Kevin, who did it all the time in ''Film/{{Tron}}''. Trapped in a lightcycle arena? Well, let's [[OffTheRails make a run for that glitch on the wall]] and hope it doesn't kill you. Lacking transport? Hot-wire a freaking Recognizer ([[DrivesLikeCrazy and crash it in the middle of downtown]]). Running around in a huge city with only a vague idea on where your new [[HeterosexualLifePartners best friend]] is heading? Mug a {{Mook}} and [[DressingAsTheEnemy change your]] TronLines to blend in. Then there's re-routing a massive amount of power using his own body as a conduit and having no plan whatsoever at the endgame other than "kiss your pal's girlfriend and jump into the monster."
---> '''Tron:''' If you ''are'' a User, then everything you've done has been according to a plan?\\
'''Kevin Flynn:''' You wish!
* Inverted with ''Film/{{Thor}}'' in that it isn't the hero, but the villain. [[spoiler:Loki allowed a few Frost Giants in Asgard for "a bit of fun" while also "protecting Asgard" from Thor's rule; talks his brother into doing something stupid but the consequences were a lot bigger than he had hoped for; then he realizes he's adopted and decides that it's better for Thor to stay on Earth while [[LoveMakesYouEvil he tries to earn their father's love]] by killing an entire race.]]
* ''Film/MillersCrossing'': "Do you always know what you're going to do before you do it?"
* In ''Film/MostWanted'', Keenan Ivory Wayans says, "I'm a Marine. We don't plan—we improvise!" Which is a shout-out to ''Film/HeartbreakRidge'', and also total BS, as Marine operations are planned in detail beforehand. Of course, one tenet of Murphy's Law reads, "No plan survives the first contact intact."
* Played with and {{Lampshaded}} in ''Film/HarryPotterAndTheDeathlyHallows Part 2'': After Voldemort learns they're hunting horcruxes Hermione says they need a new plan. Harry's response? "Hermione, since when have any of our plans ever worked? We plan, we get there, all hell breaks loose!"
* In the ''Film/MissionImpossible'' films, whenever something goes awry with plan, the improvisation is usually high in the {{HSQ}}.
* This is Bartleby's specialty in ''Film/{{Accepted}}''. When his plan to set up a fake university ends up GoneHorriblyRight, he gets up on stage and, rather than tell the truth, starts winging it, gives a RousingSpeech, and welcomes everyone to orientation. He walks into a frat party by first pretending to be a brother and taking a freshman's blazer so he can pretend to be a pledge. During the Big Damn Trial at the end, he looks expectantly at the "dean" he hired to begin the defense, only for the "dean" to look back at him and say "lead with your star witness". The only time it doesn't work is when everyone's parents show up for "Parents' Weekend" the morning after a ''huge'' party, at the same time as his archrival douchebag and the dean from the real college, and at the same time as ''the police''.
* Inverted or averted in ''Film/{{Push}}'' where the only way to conceal a plan from an enemy with mind reading powers is for the hero of the group to make a plan, write it down in the form of about a dozen instruction envelopes, and have his mind wiped. They are effectively flying as blind as if they were making it up as they go, but they end up following the plan and succeeding. Even as the characters read their instructional envelopes, [[UnspokenPlanGuarantee the audience is kept in the dark]].
* In ''Film/XMenTheLastStand'', to take down Juggernaut, Shadowcat goads him into charging at her and Leech. Leech's power nullifies the Juggernaut's, and when he slams into the wall he gets knocked out.
* ''Film/GuardiansOfTheGalaxy''
** The heroes end up doing this quite a bit; an early prison break is made with an outline of a plan, but circumstances force them to quickly improvise its implementation on short notice.
** Star Lord has "12 percent of a plan" to stop the BigBad. Rocket (sincerely!) laughs at this idea and Gamora agrees, saying that it's "barely a concept".
** At the end, [[spoiler:Peter Quill successfully delays the BigBad's imminent destruction of a planet by suddenly challenging him to a ''dance-off''.]]
* ''Film/ConAir'' provides some villainous examples, as Cyrus has planned ahead, but still has to improvise, as he couldn't have predicted every variable. {{Lampshaded}} in this exchange:
-->'''Cyrus the Virus''': *holding the pilot at gunpoint* Say there was a disturbance but you've got it under control. Say it, or I ''will'' kill you.
-->'''Pilot''': Without me you got nobody to fly the plane.
-->'''Cyrus''': I never think that far ahead.
* ''Film/{{District 9}}''. Wikus gets them into MNU headquarters, but hasn't bothered to work out how to get out again, mainly because he thinks it's a SuicideMission. Christopher has to think up a plan on the spot to save both their butts.
-->'''Christopher:''' I thought you had a way out?
-->'''Wikus:''' I didn't say anything about getting ''out!'' [[ExactWords I said I would get us]] ''[[ExactWords in!]]''

* ''Literature/TheHeroesOfOlympus'':
--> “So you do have a plan?” Octavian asked skeptically.
--> Percy looked at his teammates. “We go to Alaska as fast as possible...”
--> “And we improvise,” Hazel said.
--> “A lot,” Frank added.
* ''Literature/TheWheelOfTime''. [[spoiler:Mat due to way his luck-tweaking ability works, he does poorly at games of planning than of chance. For this reason, most of his better plans by default fall under this category.]]
* The "wizzard" Rincewind from Terry Pratchett's ''Literature/{{Discworld}}'' novels is not as concerned about where he's running ''to'' as what he's running ''from''. He notes this on several occasions. "Run!" "Where to?!" "From! The key word is from!" Which invariably leads to more running. By ''Discworld/TheLastHero'', this is what he states as his religion (main tenet: whatever happens, you can run from it). However, when running away is not an option, Rincewind does come up with some clever plans, like in ''Discworld/InterestingTimes'' having the local Dibbler clone spread a rumor that the rebel forces are NOT bolstered by [[SuspiciouslySpecificDenial 3,200,009 vampire ghosts]], nor by the vast and invincible Red Army. [[spoiler:The vampire ghosts part is false. The Red Army turns out to be true, though mostly by an accident on Rincewind's part.]] Rincewind spreads such a bizarre rumor upon realizing that while telling someone that an enormous army is coming ''does'' frighten them, it's even ''more'' effective to tell them what they ''won't'' be facing and have the ''rumors'' spiral out of proportion.
** A more heroic, for lack of a better term, Indy Ploy is the MO of Moist von Lipwig in the ''Literature/{{Discworld}}'' novel ''Discworld/GoingPostal''. Near the end, he makes a bet with the MagnificentBastard BigBad Reacher Gilt, and he has no idea how he'll win at first ... In his second appearance in ''Discworld/MakingMoney'', he outlines a grand if somewhat vague vision of the future of currency, and wonders if he should write it down so he can work out what he's talking about later. In both books the confidence with which he enters such things leads everyone else to conclude he had it all planned out.
** Lord Vetinari of Ankh-Morpork combines {{Indy Ploy}}s and ThePlan to devastating effect. It was once stated that, since you can't plan for every eventuality, Vetinari doesn't. When in doubt he will order Vimes '''NOT''' to get involved with it. Say what you will about Vetinari, he knows how Vimes will follow this trope for him. Vimes is too vimesy to use ThePlan, so one could call him Vetinari's laser-guided Indy Ploy.
* Commissar Literature/CiaphasCain, [[FakeUltimateHero HERO OF THE IMPERIUM!]] in ''TabletopGame/{{Warhammer 40000}}'', often finds himself running headlong into situations he certainly shouldn't be running into in a universe as casually lethal as Warhammer 40K. He usually fights and flees his way out of these situations by simply making things up as he goes along, improvising weapons and tactics from his surroundings and from simple ingenuity. In one case, he halts a mob of bloodthirsty, rioting Imperial Guardsmen by jumping on a table, pointing at someone, and ordering them to get a mop, as the mess they had left was simply ''deplorable''.\\
[-"Whatever they'd been expecting me to say or do, this certainly wasn't it."-]
** And, by extension, Cain's literary predecessor, Harry Paget Literature/{{Flashman}}, who lies, flatters, and flees his way through adventure after adventure, escaping by dint of sheer luck and the skin of his teeth.
** Jurgen, his assistant, is no different sometimes. He usually just carries every item of possible use he can and always just so happens that they need some of those items. While that requires some planning, his action of ramming a gun-emplacement with a truck certainty was not planned. Cain tries to find a reason to criticize him and '''''fails'''''.
* In ''Ghostmaker'', trooper Caffran, being miffed at being recalled from an assault at an enemy stronghold, manages to get an entire squad of Tanith following him into that aforementioned stronghold, almost single-handedly destroying an entire city's worth of insane Chaos-worshipping berserker fanatics by [[spoiler:setting off a large enough explosion inside the stronghold that the cultists believe the Imperial Guard have completely entered the city, and proceed to engage in a mass suicide in the name of Khorne, the Blood God.]] End result, the entire Chaos army ends up dead while the Guard troopers still haven't even gotten inside the city.
* Creator/LoisMcMasterBujold's ''Literature/VorkosiganSaga'':
** Miles Vorkosigan lives off these; he started his military career when he attempted to smuggle guns to a besieged planet in an unarmed freighter and, after a series of increasingly insane improvisations, wound up [[spoiler:in command of the enemy forces]]. And that's only halfway through his first book. Miles has thus far managed to improvise his way [[spoiler:to one of the most powerful positions in the Barrayaran empire and into marriage and fatherhood while acquiring a six-years-younger twin brother and an entire fleet of mercenaries]].
** But maybe he [[ActionMom gets it from his mother]]. After all, Cordelia starts out captured by the enemy in ''Literature/ShardsOfHonor'' and ends up [[spoiler:married into the highest levels of aristocracy and Vicerene of two planets]] before it's all said and done. Of course this is ''after'' she [[spoiler:effects a daring escape from Aral Vorkosigan]] who is kind of a [[FourStarBadAss Admiral Bad Ass]] and certainly an OfficerAndAGentleman (InSpace!).
** In ''Literature/TheVorGame'', Miles and Emperor Gregor pull off the rarely-attempted Synchronized Tandem Indy Ploy, and somehow manage to completely out-maneuver a MagnificentBastard of a {{Chessmaster}} while unable to coordinate with each other ''on opposite sides of a star system''.
* Most of Literature/HarryPotter's plans fit into this trope, mostly due to a lack of time and/or information to plan ahead. Indeed, one could argue that this is arguably his defining trait. Despite Hermione being more clever and Ron knowing more about the Wizarding World, neither are as good at thinking on their toes the way Harry is. Contrast this with Voldemort, [[TheChessmaster who meticulously plans everything]] and is a big fan of playing the long game to get what he wants. The twist though is that Voldemort has ComplexityAddiction and [[BondVillainStupidity is so egotistical it causes him to dismiss small or simple things as unimportant, giving Harry and company weaknesses to exploit.]] A notable example is his raid on the Ministry in Book 5, which basically boils down to "Grab Sirius and run," then changes to "run away from Death Eaters."
** This is also brought up in ''Deathly Hallows'':
--->'''George:''' So what's the plan, Harry?\\
'''Harry:''' There isn't one.\\
'''Fred:''' Just going to make it up as we go along, are we? My favourite kind.
*** When they ''do'' make a meticulous plan for how they're going to break into the Ministry of Magic, it goes wrong from the start, and they have to wing the whole thing. Ditto the Gringotts break-in. [[spoiler:They were not anticipating flying away on a dragon.]]
*** In book seven, there's a lengthy time where Ron and Hermione assume Harry's got a plan, and are pissed (Ron) and worried (Hermione) when they discover he hasn't got one.
*** ''Deathly Hallows Part 2'' Harry himself {{Lampshades}} it by saying there's no need for a plan: "We make a plan, we go in, all hell breaks loose!"
* In the Literature/HonorHarrington series, Victor Cachat is really good at this. He is [[TheChessmaster good at planning too]], but no plan survives an encounter with the enemy, so he's often forced to make things up as they go. And [[TheDeterminator does he make them]]...
** Honor herself fits this description exactly. Up to TheChessmaster and TheDeterminator parts, though she usually has more resources to pad for contingencies better.
* Clockpunk of "Literature/ClockpunkAndTheVitalizer" is basically forced to do it once she's been captured. To her credit, though, she manages to [[spoiler:injure The Vitalizer and escape his clutches]] because of her quick thinking.
* Roland Deschain of Creator/StephenKing's ''Franchise/TheDarkTower'' series is a great advocate of Indy planning. He prefers them to totally thought out rigid plans because rough spontaneous ones leave room for improvisation, something he does very, very well indeed.
* In ''Literature/TheThrawnTrilogy'', Luke Skywalker has an impressively long run of "This isn't working, I'll try something else" when he's pulled out of hyperspace by an Imperial Interdictor. Condensed, here's about half of it: "Whoa, it's practically on top of me! I'm in tractor range, I can't go to lightspeed in this gravity well, and they're hailing me. There's a freighter with it, there are no living things on board. Where's the nearest edge of the gravity well - gun for it. The freighter is between me and them, I'll send a timed proton torp to blow up the freighter, debris should shield us, okay done - damn, they're moving to keep me in the gravity well, I'll go laterally - tractored! They'll pull us in, if I can change speed I can get it to let go, I'll swing to get as close to the edge of the gravity well, then reverse-trigger the inertial compensator at full power - there, dead stop, the tractor's not on me for just a moment, I'll fire proton torpedoes to be caught by the tractor and pulled in. Done, fly! They're finally firing on me, we're far enough away, jump to lightspeed! ...We're out of range, but we've fallen out of lightspeed and now we're stranded in lightyears of empty space. Hyperdrive is dead, subspace radio is broken, we can't leave, aren't likely to be found, and can't call for help. Okay [=R2=], let's try..."
** The ''ComicBook/XWingSeries'' has Wraith Squadron. A dozen people, give or take, constantly find themselves in situations that plans could not have predicted and rapidly put together schemes, often rather complex ones, to get the desired results. For about a thousand pages worth of novels. No wonder the BigBad was afraid of them. And their allies, too, for that matter.
*** In their first live battle, Wraiths Five and Six, plus two A-Wings, manage to trick an Imp Star Deuce into following them, by pretending to be the Millenium Falcon. How they do so involved precision flying, wavery shields, an obsolete battle encryption that the enemy didn't know that they knew that the enemy could crack, and a bad imitation of Leia saying that Han was up to his elbows in the remains of the hyperdrive and couldn't talk right now. Just to top it off, they later ended up in the command of the inimitable then-General Han Solo himself. The loonies are running the asylum, and damn if it ain't fine.
** Consider what happened within the first seven pages of ''Literature/{{Allegiance}}''. Han and Luke in the Falcon lift off a planet, are attacked by pirates, do some tricky shooting and maneuvering, and a Star Destroyer glides into the system to take care of the rebel cell being smuggled out by the Falcon. Han powers down the Falcon's weapons and sends out a general emergency call, nominally to the planetary defenses below. The Star Destroyer tells him to state his intention and emergency, Han says that they're a medical mercy team sent out in response to a groundquake on the planet and were attacked by pirates. The Star Destroyer quickly and systematically destroys all of the pirates and tells Han that the planet is now under Imperial interdiction. Go home until the block has lifted. Han makes a show of reluctantly agreeing, and as they fly away he remarks to Luke that it's nice to obey Imperial orders now and again.
** Creator/TimothyZahn in general likes having his protagonists get pinned down and forced to improvise repeatedly to escape. The Cobra trilogy especially is packed with this.
* Done many, many times in ''Literature/{{Animorphs}}''. A notable example is #37 ''The Weakness'', where Rachel, the group's AxCrazy member, takes over the Leader's role. Her 'plan' to get into the enemy's stronghold involves stealing a private jet and crashing it into a building.
** For most of the run, ''Animorphs'' might as well just be called Indy Ploy: The Series. To be fair they do frequently ''try'' to plan everything out, but when things inevitably go downhill they just start making crap up as they go, with a result of all of them becoming really proficient. Another notable example is in #29, when everyone except Cassie gets knocked out with alien flu, forcing her to Indy ploy her way into the Yeerk pool to rescue a yeerk who knows too much before escaping to perform on the fly ''brain surgery''.
* ''Literature/TheHollows'': Rachel Morgan tends to rely on these, while Ivy is [[CrazyPrepared the polar opposite]].
-->'''Rachel:''' "Jenks, plan B!"\\
''Later, outside.''\\
'''Jenks:''' "So what's plan B?"\\
'''Rachel:''' "Grab the fish and get the hell out of there."
* ''Literature/GentlemanBastard'' series: Locke Lamora tends to have his plans explode due to unforeseen complications, but he's ''very'' good at improvising. At one point he has lost access to his wardrobe and all of his disguises and needs to pass himself off as a wealthy merchant to his mark. Through a quick, complicated scam, he ends up walking into a bank and coming out half an hour later wearing the clothing of ''the man who runs it''. And he only tried the ridiculous scheme after the first two, simpler ones failed miserably due to the security procedures of the bank manager... which he then turns around and uses on his successful attempt.
** In fact, he had to have his inclination to conjure audacious, ridiculous schemes from nowhere trained out of him by his master; before that his ''default'' plan was "Uhhhh...", which, as his master points out, is not consistently workable in the long run.
* ''Literature/EndersGame'': The Dragon Army, anyone?
** Flying unshielded ships at a planet after losing every engagement?
** This is in contrast to Ender's brother Peter, who is very fond of the XanatosGambit and BatmanGambit, and has the ability to pull them off.
** The commanders of Battle School note that this is most probably what their near-AI level "Fantasy Game" computer is doing when Ender wins an unwinnable minigame. The game is creating brand-new areas and scenarios based off of what it has learned of Ender's mind. While it was programmed to tailor scenarios to individual players, it doing something of this scale was wholly unprecedented, leading to cries of "How in the hell did the computer ''do'' that!?"
* David Weber writes in an [[http://baencd.thefifthimperium.com/13-TheBalticWarCD/TheBalticWarCD/Interstellar%20Patrol/0743436008___1.htm introduction]] to Christopher Anvil's ''Literature/InterstellarPatrol'' stories:
-->An Anvil character triumphs by shooting the rapids, by caroming from one obstacle to another, adapting and overcoming as he goes. In many ways, his characters are science-fiction descendants of Odysseus, the scheming fast thinker who dazzles his opponents with his footwork. Of course, sometimes it's a little difficult to tell whether they're dazzling an opponent with their footwork, or skittering across a floor covered in ball bearings.
* ''Literature/TheDresdenFiles'': Harry Dresden will often start out with a general plan, but seeing as how the entire universe appears to hate him violently, this usually goes to hell fast. Thus we get a lot of plans that amount to "arrange for some backup, confront the villains, and wing it from there," and in one case even "get [[MeleeATrois everyone]] in the same place and see what happens." It gets to where it's a real surprise when, in ''Changes'', his elaborate scheme to break into a building and steal information goes off without a hitch. Some examples of his make-it-up-as-I-go-plans:
** Oh, crap, giant scorpion-golem is attacking me and I can't use fire on it! Okay, [[spoiler:drop a freaking elevator on it using a tunnel of wind]]!
** Trapped in a vampire's mansion, stripped of my gear, girlfriend is being held hostage, facing dozens of vampires, the leader of whom can wield magic, and [[ArsonMurderAndJaywalking I'm wearing undies with yellow duckies on them]]. Shit, what do I do? [[spoiler:Pour magic into the shades of the vampires' hundreds of victims, giving them enough strength to mob the vampires and rip them to pieces]], that's what.
** Surrounded by Faerie assassins in a Walmart with mind-numbing fog cutting off all help save [[BadassNormal Karrin Murphy]], and the bad guys are immune to my magic. [[spoiler:Gasoline, a Super-Soaker, and chainsaws]] are the solution.
** Facing off against a terrorist empowered by a FallenAngel on top of a train, by myself. Nothing I throw at this guy works, thanks to the magical noose around his neck that instantly heals all damage. [[spoiler:Well, let's give that noose a grab....]]
** Three powerful necromancers who outpower me and are backed up by armies of unstoppable undead minions. I'm hurt, tired, and in no shape to face them head on, but the ritual they're planning will kill thousands if I don't stop them. Well, good thing I'm in the Field Museum. [[spoiler:Let's raise that T-Rex skeleton and get to whupping some undead ass.]]
** In fact, Harry's tendency to wing it instead of creating a cunning plan saves him at least twice, by making potential adversaries who are accusing him of being an Evil Mastermind think about his standard M.O. Rashid the Gatekeeper's response is to practically double over with laughter; Fix the Summer Knight's response is more "OhCrap"...
*** Or when he's the target of a Summer Fae that doesn't "really" want to get in his way but has to because of direct orders. [[spoiler:And he uses his previously given boon to ask said Fae to get him a donut just to get him out of his way long enough.]] Not really a "plan", but he sure as hell didn't think that one through.
** In fact, it's a mark of his CharacterDevelopment that he slowly shifts from the IndyPloy to XanatosSpeedChess and starts preparing things ahead of time. The examples mostly take place over the first few books, while notable examples of his planning ahead include ''Literature/DeathMasks,'' ''Literature/SmallFavor,'' ''Literature/TurnCoat,'' and ''Literature/SkinGame.'' As he lampshades, [[SquishyWizard wizards in general are much physically weaker than many of their enemies,]] and so the supernatural baddies will generally try to ambush him to get him out of the way. But once he has time to plan...
* ''Literature/TheMemoryWars'' sees its hero, Nathan Shepherd, spend a lot of his time doing this.
* Literature/HoratioHornblower is guilty of both this and XanatosSpeedChess. Although, being a Napoleonic Wars-era Naval officer, and the timing of military operations being dependent upon friction--wind, rain, sea conditions, road conditions, partisan attacks, the idiot who got drunk last night, et cetera--he has no way of predicting for certain the movements of his enemies, even if he knew what they intended to do. And he's generally brilliant at it, so really no reason to complain.
* Fisk's rescue of Michael in the first book of the ''Literature/KnightAndRogueSeries'' goes like this: Pull off a scam to get brought in, convince the evil baroness to let him stay the night, search for Michael once everyone has gone to bed, then find some way to get the hell out of there with both of them alive and whole.
* In ''Literature/TheHobbit'', the Dwarves seem to mostly operate this way, dealing with every obstacle as they happen. This becomes a problem late in the book, when they turn out to have no plan for getting rid of Smaug, which Bilbo doesn't find out until after they've already pissed him off by stealing from him.
-->They debated long on what was to be done, but they could think of no way of getting rid of Smaug--which had always been a weak point in their plans, as Bilbo felt inclined to point out.
* There is a story by Creator/RobertSheckley about the human fleet is at an extreme disadvantage against the alien fleet, with both sides having perfect tactical computers. The humans shut their computers off and attack without a pattern, by putting someone who's gone completely loopy to push all the pretty buttons. The aliens are mostly just sitting there while being shot at because their computers are not giving any tactical analysis since they can't see a pattern.
* From ''[[Literature/SixteenThirtyTwo 1635: The Cannon Law]]'':
-->"Plans? Faugh. The playthings of lesser intellects. I, Ruy Sanchez de Casador y Ortiz, need no plan. Insult me no futher with such talk, Señor Simpson."
* ''Literature/TheExilesViolin'': Jacquie knows she should have a {{plan}} before taking action but she's no good at planning so she wings it instead. This gets her in trouble during a infiltration and on another occasion she regrets her habit of having goals instead of plans.
* In ''Literature/ThePrinceOfThorns'' this is how basically all of Jorg's plans go. In the second book this is enforced; mind readers are spying on him, so whenever he has a good idea or sets something up he puts the knowledge of it into a magical box that removes it from his memory. The echo of the idea remains so that when it's time to put it into effect he knows to retrieve it from the box.
* In ''Literature/VampireAcademy'', this is Rose Hathaway's usual tactic for getting out of situations. She is fast-thinking but acts without a long-term plan. Like, for example, forming an immediate escape plan in Portland, once her and Lissa's cover is blown, one involving borrowing a car and running off to Los Angeles to get lost in the crowd. It works most of the time, but she also has remarkable luck.
* In the ''Series/DoctorWho'' novel [[Recap/NewSeriesAdventuresEnginesofWar "Engines of War"]], the Doctor says to Cinder he's not good with long term plans and prefers "Winging it".
* Discussed in ''Put a Lid On It'' by Donald Westlake. The narrator — a career criminal — notes that criminals in movies tend to have all kinds of elaborate plans involving timetables, [[PlanningWithProps scale models]], and so on. On the other hand, [[ThisIsReality nobody he knows does that]]; they all tend to just show up with a vague idea of what they need to do and improvise from there. This is partly because "the situation... is never exactly, precisely what you thought the situation was going to be." But he also notes that:
-->[P]eople who make plans in their lives and people who make robberies are two pretty distinct character types. People who make plans are likely to make plans that eliminate the necessity of having to make a robbery in the first place.
* While the title character in ''Literature/EdenGreen'' prefers to have a detailed plan ready for everything, the alien needle monsters invading her city often force her to come up with ideas on the fly just to stay alive.

[[folder:Live Action TV]]
* ''Series/GameOfThrones'': Tyrion, in particular, is a master of these. Half his gambits simply seem to come completely off the top of his head, and he gets away through a combination of quick wits, a razor tongue, extensive knowledge of everyone's weaknesses, and sheer balls. The other half are meticulously planned out deceptions.
** His escape from the Eyrie is one.
** Of note is when he blackmails Lancel into becoming his mole. There's no indication that he even ''planned'' it. Lancel shows up at his door, and in the middle of the subsequent conversation, Tyrion just seems to decide; ''"I need a mole. You fit." (blackmail ensues)''.
** He pulls of a masterful one when he convinces Cersei that she indeed has his mistress captive even though she has captured Ros instead of Shae in "The Prince of Winterfell". When she brings Ros out so Tyrion can see that she is really alive, Tyrion plays along and pretends she really is the one he loves, keeping Cersei ignorant about Shae. You can actually see the wheels turning in his head as he figures out how to play this.
* ''Series/{{Psych}}'': The concept of the entire series
** "The Old and the Restless"
--> '''Henry''': My son, the super sleuth, can't even get himself access into an old folks' home.
--> '''Shawn''': No, no, no, Dad. You have no idea what we're up against, okay? I tried everything. I tried the whole "I'm a travelling doula" bit, the "dingo ate my baby" routine, "hiding Gus in a sack" trick, which never fails...

--> '''Henry''': Alright, look. What the hell are you guys doing here?
--> '''Gus''': This is the part where you get blindsided with Plan B. It's kind of fun when it's not happening to me.

* When he originally came up with the idea for ''Series/MissionImpossible'', creator Bruce Geller imagined EVERY episode's plan to go wrong at some point, leaving the IMF team to work from scratch. In the actual series, only a few Indy Ploy moments come up, mostly in the "Personal story" episodes.
** In "The Legend", season 1, the team is set to assassinate Martin Bohrmann, who's been living in South America. Briggs infiltrates Bohrmann's bedroom -and discovers it isn't that simple. They have to change the plan on a dime.
** In the 1988 relaunch of the series, the pilot episode featured John [=DeLancie=] as an assassin who intentionally used Indy Ploys: he never chose how he'd kill his target until the very last moment, improvising his plans as he went along, specifically to not be predictable.
*** This was a redo of an episode from the original series in which he assassin was played by RobertConrad.
* At the very end of the final episode of the TV run of ''Series/{{Angel}}'', the title character, faced with an [[BolivianArmyEnding approaching horde of monsters]] and asked by a teammate what he has "in terms of a plan?" [[LampshadeHanging sums up]] the team's strategy for the past five seasons:
--> '''Angel:''' We fight.
--> '''Spike:''' Bit more specific?
--> '''Angel:''' Well, personally, I kinda want to slay the dragon. Let's go to work.
** Earlier there was this reaction to learning that Gunn's plan to expose (zombie) cops who were attacking people was to go videotape them attacking him.
---> '''Wesley:''' That cannot possibly be his plan.
---> '''Cordelia:''' Hey, Gunn graduated with a major in Dumb Planning from Angel University. He sat at the feet of the master, and learned well how to plan dumbly.
*** Specifically, Angel at one point had a plan to sneak into Wolfram & Hart with Gunn's help.
---->'''Gunn:''' We know. It's cool. He's got a plan.
---->'''Wesley:''' A plan?
---->'''Angel:''' Yeah. I get to the offices before they can stop me.
---->'''Gunn:''' See? {{beat}} What? ''That's'' the plan? Walking real quick was the "plan"?
** Then there's Spike:
---> '''Spike:''' I had a plan! A good plan! ...but then I got bored!
*** Subverted in that when Spike first shows up on ''Series/{{Angel}}'', he really ''does'' have a plan, and only ''pretends'' to get bored halfway through.
* Hannibal "I love it when a plan comes together" Smith on ''Series/TheATeam''.
* Series/{{Chuck}} Bartowski doesn't have training as a spy so he really does just make it up literally from minute to minute. And sometimes..it '''works'''.
** In "Chuck vs the Ring Part II'', this is played straight and verbalized when Morgan and Awesome arrive to rescue Chuck, Sarah, and Casey from Shaw.
---> '''Morgan:''' "No plan? Never stopped me before."
* ''Series/{{Community}}'' has Jeff attempting this, only for the rest of the group to get mad when they realize he's making up the plan to grift a grifter as he goes along and in fact has no idea what his actions are even supposed to achieve. He defends himself by pointing out that he's been with them constantly since he agreed to help; when did think he had the chance to work out a plan then conceal it from the rest of them?
* The Doctor in ''Series/DoctorWho'' has a tendency to play things by ear -- [[LampshadeHanging lampshaded]] several times in the series, in moments where he's been just as surprised as everyone else that a plan of his has actually worked, or worked for the wrong reason. Being able to intuitively perceive all the possibilities of time and space probably gives him a particular advantage at this game.
-->'''Mickey Smith''': You're just making this up as you go!\\
'''The Doctor''': Yuuuuupp! But I do it brilliantly!
** And not to mention this famous exchange...
--->'''The Doctor''': This is what I'm gonna do: I'm gonna rescue her. I'm gonna save Rose Tyler from the middle of the Dalek fleet, and then I'm gonna save the Earth. And then, just to finish you off, I'm gonna wipe every last stinking Dalek out of the sky!
--->'''Daleks''': [[AC:But you have no weapons! No defenses! No plan!]]
--->'''The Doctor''': Yeah, and doesn't that just scare you to death?
** The exception here being the Seventh Doctor, who was ''always'' executing a plan of some kind, in true {{Chessmaster}} fashion. Of course, his life being what it was, those plans usually required some [[XanatosSpeedChess "on site adjustments"]].
** The Third Doctor certainly says something along those lines in "[[Recap/DoctorWho20thASTheFiveDoctors The Five Doctors]]":
--->'''Sarah Jane:''' Look, do you think this is wise, Doctor? I mean, well, whatever's in [[EvilTowerOfOminousness that Tower]], it's got enormous powers and... well, what can we do against it?
--->'''The Doctor:''' What I've always done, Sarah Jane: improvise.
** The Fourth Doctor [[LampshadeHanging hangs a lampshade]] on his improvisational skills in one episode:
--->'''The Doctor:''' I'm warning you: I'm very dangerous when I don't know what I'm doing...
** The Eighth Doctor concurs in the [[Literature/EighthDoctorAdventures EDA]] book ''Coldheart''.
---> ‘I never have a plan. Plans can go wrong. That’s why the villain never wins – villains always have a plan.’
*** And in ''The Deadstone Memorial'', his companion Fitz knows how this works:
--->‘I’m not sure where we’re even going,’ Harris panted.\\
‘The Deadstone memorial,’ Fitz answered confidently. ‘The Doctor’s going to sort all this out for good.’\\
‘How’s he going to do that, then?’\\
‘He doesn’t know yet,’ Fitz replied grimly.
** The Eleventh Doctor isn't any better:
---> '''The Doctor:''' River, you 'n me, we're gonna find the primary flight deck,[...] stabilize the wreckage, stop the angels and cure Amy.
---> '''River:''' How?
---> '''The Doctor:''' I'll do a thing.
---> '''River:''' What thing?
---> '''The Doctor:''' I dunno; it's a thing in progress. Respect the thing.
*** From the exact same episode:
----> '''The Doctor:''' Anyway, that's not the plan.
----> '''River:''' There's a plan?
----> '''The Doctor:''' I don't know yet; I haven't finished talking.
*** From yet another Eleven episode:
---> '''Amy:''' Please tell me you have a plan.
---> '''The Doctor:''' No, I have a thing. It's like a plan, but with more greatness.
*** And from yet another Eleven episode:
---> '''The Doctor:''' Need a proper look. Got to draw its fire. Give it a target.
---> '''Amy:''' How?
---> '''The Doctor:''' You know how sometimes I get these brilliant plans?
---> '''Amy:''' Yeah?
---> '''The Doctor:''' Sorry... ''(Jumps from out of hiding)'' LOOK AT ME I'M A TARGET!
*** In another instance from that episode, "The Pandorica Opens", the Eleventh Doctor threatens ''all'' of his enemies by saying that he has no weapons, nothing to lose and ''no plan'' whatsoever....so they should really do the smart thing and let someone else come up against him first.
*** The Eleventh Doctor [[LampshadeHanging lampshades]] this trope again in the 2011 Christmas Special.
---> '''Lily:''' What do we do?
---> '''The Doctor:''' No idea. Just do what I do: hold tight and pretend it's a plan.
*** In the commentary for the series 5 opener, "[[Recap/DoctorWhoS31E1TheEleventhHour The Eleventh Hour]]", [[Creator/StevenMoffat Steven Moffat]] describes the Doctor as the sort of person who would jump off a building and work out what to do about it on the way down. Moffat would much later write "[[Recap/DoctorWhoS35E11HeavenSent Heaven Sent]]" – part of the series 9 finale – which featured the Twelfth Doctor doing almost exactly that.
** In "The Return of Doctor Mysterio", the Twelfth Doctor's 'plan' at one point consists of literally randomly mashing buttons on a spaceship control panel.
** Also inverted with the Daleks and the Movellans. They were both so good at ThePlan that when they came up against each other they found themselves locked in a stalemate of XanatosSpeedChess, neither able to ever gain an advantage over the other. The Daleks realize that they need Davros to find them a way past this block, and the Movellans realize that the Dalek task force sent to the desolate Skaro must be there for some ancient, hidden thing of great importance to the current situation and set out to stop them. Upon learning what the Daleks' plan is, the Movellans want the Doctor to give them the ability to carry out an Indy Ploy just like the Daleks want Davros to do for them. Fortunately, the Doctor and the humans the Daleks brought as slave labor manage to not only destroy both of them, but capture Davros for trial.
* Sarah seems to pick up this trait from her old mentor, given this exchange from the first episode of ''Series/TheSarahJaneAdventures'':
-->'''Maria:''' Do you mean you haven't got a plan? Nothing?
-->'''Sarah:''' No. The people I fight have plans and weapons but I don't. It's what makes me different.
* ''Series/{{Farscape}}'': John Crichton lives for the Indy Ploy, which is fortunate, because the Uncharted Territories throw monkey wrenches into it every damn time. Near the end of the series, D'Argo wonders why things never go smoothly, to which John replies, "Murphy's Law."
-->'''John''': Go on, keep movin'. I got a plan.
-->'''Aeryn''': Don't tell me you have a plan.
-->'''John''': What's wrong with them?
-->'''Aeryn''': They never work.
-->'''John''': Damn these doors. They always work.
-->'''Aeryn''': Not the way you detail them.
-->'''John''': Hey, look, I get results. You're hung up on details!
-->'''Aeryn''': Your plans never work!
** And this exchange from season 2:
--->'''Aeryn''': Would you like to learn how to do this, or are you content to continually display your ineptitude?
--->'''John''': My ineptitude? You mean my improvisation, the kind that bails your sorry milita--
*** Or this one, when trying to attract the villain's attention:
---->'''John''': I know you can see me. Bad guys can always see me. That's because my plans suck.
* Mal Reynolds from ''Series/{{Firefly}}'' also has to do this a lot, as his [[ASimplePlan simple plans]] go wrong with such regularity that you could set your watch to his cries of:
-->'''Mal:''' It never goes smooth. Why don't it ever go smooth?
** Similarly {{Lampshaded}} in this exchange:
--->'''Zoe''': Captain'll come up with a plan.\\
'''Kaylee''': That's good, right?\\
'''Zoe''': It's possible you're not remembering some of his previous plans.
** Also:
--->'''Mal''': I don't plan on any shooting taking place during this job.\\
'''Jayne''': Yeah, well, what you plan and what takes place ain't ever exactly been similar.
** As Shepherd Book points out, Mal has a ''way,'' which is better than a plan.
** When something has gone terribly awry, and he is forced to come up with another plan:
---> '''Mal''': This is all part of our new plan.
---> '''Kaylee''': How exactly is--
---> '''Mal''': Still workin' the details.
** Mind you, when he finally comes up with a plan in ''Serenity'', it's so utterly horrifying you start to understand why he doesn't do it more often.
---> '''Mal''': I start fighting a war, I guarantee you'll see something new.
* ''Series/{{Leverage}}'' is fond of using these after the original plan goes awry. Prime examples include "The Beantown Bailout Job" and "The Ho Ho Ho Job".
** Ford isn't known as a mastermind for nothing. In fact, a lot of times this "improvisation" is just another part of ThePlan of the episode.
* Dr. Series/{{House}}. As brilliant a doctor as he is, makes it up 98% of the time.
* This was Series/MacGyver's usual Modus Operandi. It was also {{Lampshaded}} several times:
-->'''Murdoc:''' You know, [=MacGyver=], that's why you're so hard to beat. Nobody knows what you're going to do next. Including you.
* The characters in ''Series/StargateSG1'' and ''Series/StargateAtlantis'' live by these. Sometimes even they're shocked their plans work...
** Especially O'Neill. Then again, that could just be the actor noting how small the distance really is from his previous role in ''Series/MacGyver''.
** [=McKay=] is asked at least once per episode to find a way to fix the problems cause by someone's failed plan, oftentimes Sheppard's or his own.
---> '''[=McKay=]:''' "I'm Dr. Rodney [=McKay=], alright? Difficult takes a few seconds; impossible, a few minutes."
** In ''Series/StargateUniverse'', this is O'Neill's expectation of Young, who is stuck with his people on a barely-functioning ship ''galaxies'' away from home. Guess it must be a requirement of all [=SGC=] personnel, given what they have to deal with.
* In the ''Series/StarTrekTheNextGeneration'' episode "Attached", Picard and Crusher are psychically linked and on the run from the aliens du jour, and so she's able to call him on pretending to know where they're going; he claims that it's important for TheGoodCaptain to sometimes project the image of understanding and confidence in dangerous situations.
** One of the reasons ''Franchise/StarTrek'' is so popular is because even the smart characters have no qualm with junking the manual and making it up as they go. Both Kirk and Picard were masters of making stuff up and making it look good. Closely followed by Spock and Riker. Even [=McCoy=] got in on it during "[[Recap/StarTrekS2E1AmokTime Amok Time]]" -- within ten minutes of the revelation that Kirk and Spock were supposed to fight each other to the death, he's come up with a plan to thwart it.
** This tendency is [[LampshadeHanging elaborated in hilarious detail]] by Voltaire's filk "U.S.S. Make Shit Up".
* ''Series/StarTrekVoyager''. In "Basics", Voyager has been seized by the Kazon and Tom Paris (who was away in a shuttle at the time) is trying to convince some aliens to help take it back. They're reluctant, so Tom gives a BadassBoast that he knows Voyager inside-and-out, and has a cunning plan to boot. The aliens promise to rendezvous with Tom in an hour. After they've broken the connection, Tom says, "Well that gives me an hour to think of a plan!"
** And he does. And it works.[[note]]Though partly due to luck; the Doctor, a key piece of the plan, was taken offline, but the Kazon had missed one of the Voyager crew who was able to carry out the inside part of the plan.[[/note]]
* The [[BigBad evil masterminds]] of ''[[Series/TwentyFour 24]]'' constantly have their {{Evil Plan}}s foiled by Jack Bauer's {{Indy Ploy}}s. The man hitched a ride on the bottom of a garbage truck ... no, you're not going to beat a man like that with anything less than nuclear weapons. (And actually, not even then).
* ''Series/BurnNotice'' knows how to play this one, too. Westen usually has multiple plans, yet they frequently resort to throwing them all away and improvising on the spot. For instance, :
--> '''Max''': What's going on here? Do we have a plan?
--> '''Michael Westen''': A plan, no, I... got some tactical goals, and a rough approach?
--> '''Max''': A rough approach, well, that's terrific. Thank god we got that, because we don't have backup, video feeds or working coms.
--> '''Michael''': Welcome to my world.
** In one particular episode, Michael's plan to capture a bad guy relied on getting close to him and using that position to maneuver him into a position in which he could capture him with little difficulty. When that failed due to Michael being exposed as a fake, he decided that they didn't have enough time to come up with a new plan (which probably wouldn't work anyway since the bad guy had seen everyone in Team Westen), broke into the bad guy's hotel room, clubbed him over the head and dumped him into a truck for delivery to the authorities.
** That said, when his plans work ''well'', they're a sight to behold. When his plans are ''improvised'', almost without exception, ''they're even better''.
* ''Series/{{Frasier}}'''s many convoluted {{Farce}}-structured episodes often involved ''extremely'' fast-paced DisasterDominoes, [[ASimplePlan Simple Plans,]] or {{Fawlty Towers Plot}}s that required the characters to frantically come up with new ideas as they were swept along with the action to keep their plans from descending into havoc. Naturally, because it was a comedy where no one gets killed, this only made the hijinks and misunderstandings infinitely worse, as TooManyCooks spoil the broth, and they had to inform everyone else about all their new schemes and lies in addition to the list of volatile situations they were juggling. One would expect they wished twitter existed in the '90s, but on the other hand, they could often be downright ingenious at improv...
* Callen's plan in the season 3 premiere of ''Series/NCISLosAngeles'' consists of "Save Hetty." That's it.
* Danny Quinn in ''Series/{{Primeval}}'' likes to do this a lot, especially when he's disobeying orders. His best one was getting into a helicopter and making a huge ''Giganotosaurus'' chase him through the time portal.
** Then he returns without the helicopter.
--> "Do you want me to go back and get it?"
* ''Series/PersonOfInterest'': Reese occasionally falls back to this when the situation is too dire or Finch is somehow unable to help him for whatever reason. He's very good at it.
* Danny's specialisation in ''Series/{{Hustle}}'', as opposed to [[TheChessmaster Mickey's]] careful planning.
* This seems to be the modus operandi of Harmon Rabb from ''Series/{{JAG}}'', no matter whether it is in a fistfight, in the cockpit, or in a courtroom.
* This happens all the time on ''Series/TeenWolf''. Scott and Stiles especially tend to end up just winging it.
-->'''Stiles:''' Okay, one question: what are you gonna do if the Alpha doesn't show up?
-->'''Scott:''' I don't know.
-->'''Stiles:''' And what are you gonna do if he ''does'' show up?
-->'''Scott:''' I don't know.
-->'''Stiles:''' [[{{Beat}} ...]] Good plan.
* Fairly common in ''Series/{{Supernatural}}'', as half the time the monster they're dealing with turns out to be a different creature than they expected, or operating in a different way than they expected. You can also bet that if they find and torch the bones of a ghost twenty minutes into the show, [[SpoiledByTheFormat then that's not how to stop that particular ghost]].
** Employed hilariously in season five:
--->'''Bobby:''' Okay. First truck don't leave for an hour. We get in, [[StuffBlowingUp we plant the c-4 every 25 feet]], then we pull the fire alarm.
--->'''Castiel:''' [[InstantlyProvenWrong That truck is leaving.]]
--->'''Bobby:''' Balls! Okay, new plan.
* ''Series/{{Timeless}}'': The team goes back in time to keep criminals from altering history. After it becomes clear history has already been altered, they decide to wing it. At the end after the disaster happens anyway, just in a different manner, Lucy says maybe they can't just make it up as they go along.
* This is the beating heart of ''Series/CutthroatKitchen''. The general idea is that it's a competitive cooking show where Alton Brown periodically auctions off "sabotages" that severely complicate someone's planned recipe, forcing the chef(s) on the receiving end to come up with a workaround to produce something vaguely similar to the required dish - with a thirty minute time limit on cooking to ratchet up the tension (which is already pretty high, especially when one of the chefs has never actually made the required dish before). Then, once the dust has settled, they need to justify the result to the judge without at any stage admitting to having been sabotaged. If it wasn't for hastily improvised substitutions to cover for a key ingredient being stolen or the replacement of the usual heating tools with a burning bathroom sponge or something, nothing would ever get done.
* In ''Series/TheFlash2014'', this is Captain Cold's approach to a heist.
-->"There are only four rules you need to remember. Make the plan, execute the plan, expect the plan to go off the rails… throw away the plan."

* ''Radio/OurMissBrooks'': In the episode ''April Fool's Day'', Miss Brooks attends an "Everybody Must Do Something Party". [[spoiler:She stalls for time to avoid Miss Enright embarrassing her with an April Fool's Day joke. Miss Brooks plays the ukulele, sings, recites poetry, finally resorting to reading the phonebook aloud.]]

[[folder:Tabletop Games]]
* If you give a thought about it, this is the way that luck of heroes work in ''TabletopGame/DungeonsAndDragons''.
* TruthInTelevision for every [[TabletopRPG GM]] who's ever [[SchrodingersGun avoided]] [[OffTheRails railroading]].
** Most players too. Your plan will go horribly wrong at the first step, or you don't even bother with a plan in the first place; either way, you'll end up winging things.
** Also the standard plan for most Shadowrunners In-and-Out of Universe.
* Adorjan's Excellency in ''TabletopGame/{{Exalted}}'' specifically can't enhance anything that's planned out in advance, meaning that anyone using said Excellency has to use these on a regular basis.
* A common feature of every tabletop wargame, be it ''TabletopGame/{{Warhammer}}'', ''TabletopGame/IronKingdoms'' or anything else. Sometimes you just lose a lynchpin of your strategy on turn one or two - your mech takes an unlucky hit and is crippled, your wizard decides to explore a new career as [[BalefulPolymorph a frog]] or [[MagicMisfire a smoking crater]] containing SmolderingShoes, your reserves are delayed, your tanks are stuck in an unfortunate terrain feature - and you have to wing it from there.
* Common strategy in ''TabletopGame/{{Warhammer 40000}}'', most notably from the Orks and the Space Wolves. The Space Wolves, at least, are quite bright under their [[ObfuscatingStupidity mostly feigned]] barbarian attitudes, meaning that they ''can'' have plans, they're just also really good at ad-libbing when it all goes to hell. The Orks, on the other hand:
-->"Here's da plan: win. If we lose, it's 'cause ya didn't follow da plan."
** A Boss with any chance of significant success has to be Kunnin' enough to put decent strategies together, but beyond those broad strokes, he and all his nobz and boyz will be implementing Indy Ployz that consist mainly of krumpin' everything in sight.

* [[Myth/ClassicalMythology Heracles/Hercules]] was a ''master'' of this, especially in the course of his Twelve Labors. When he found out that the Nemean Lion's hide was impervious to weapons, he strangled it. To fight the Hydra, which could grow its heads back, he (or one of his friends, at his request) seared the stumps [[KillItWithFire with a torch]]. And to clean up the enormous and never-cleaned Augean Stables, he uses his strength to ''alter the course of two nearby rivers''.
** There were originally only ten tasks, those last two were disqualified for exactly the ploys he came up with. Of course, since the tasks were meant to kill him the ploys still work.
* Sir Gawain from [[KingArthur Arthurian mythology]] once held off a massive angry mob while using a chess board as a shield. Not to be outdone, the damsel he was protecting started chucking the pieces (which would have been made of carved stone) at the mob. She knocked a few people out before the whole affair was through.

* ''Theatre/SeventeenSeventySix'' portrays the founding of the United States as one gigantic, out-of-control, earth-changing Indy Ploy. [[TheMusical With singing and dancing.]]
* In ''Theatre/JacobMarleysChristmasCarol'' most of what Marley tries to win Scrooge over is improvised on the spot.

[[folder:Video Games]]
* The characters in ''VideoGame/TheWalkingDead'' video game series by Telltale generally come up with things on the fly. Most of the time, they'll ''have'' a plan, but it always gets thwarted, either by walkers overwhelming them or somebody deciding to act at ''just'' the wrong moment. Season 1 has the group plan to get a boat and head out to sea, but beyond that, they wing it. Season 2 deconstructs it when Kenny suggests that "we'll make it up as we go," only to be admonished by Mike, who says that "you can't plan to improvise."
* ''Franchise/AceAttorney'':
** The titular Phoenix Wright is essentially the videogaming world's avatar of this trope. Both he and his successor Apollo Justice rely almost exclusively upon plans built upon the Indy Ploy; especially on the first day of court when they usually have no clue who the real culprit is. Repeatedly, the decision to have new information added to a testimony involves the player character thinking something to the effect of 'if only I knew where I was going with this'.
** Although this is completely averted in the last case of the first game, when Phoenix tricks the BigBad by not only making them [[spoiler:incriminate themselves, but also provide a legal reason as to why the evidence Phoenix collected in an unauthorized investigation can be presented in court]] all without said big bad knowing it. Phoenix very clearly states on multiple occasions during the final part of the case that he had planned it all out. In fact this plan will actually fool not only the BigBad, but ''players themselves'', resulting in a large percentage of people getting a game over on their first run through, due to being tricked by Phoenix (Part of the plan was to refuse to do something that 99% of players would naturally assume they had to do, thus resulting in them picking the wrong opinion). It turns out he CAN plan things out after all.
** However, in the fourth game where the aforementioned Mr. Justice is the main character, Phoenix seems to have taken up [[BatmanGambit a new way of doing things]].
** ''Apollo Justice'' also happens to be the game where this trope is actually [[DeconstructedTrope deconstructed]], since the BigBad's plot to [[spoiler:get Phoenix disbarred]] actually depended on the fact that Phoenix would be flying by the seat of his pants. The rest of the game, while playing it straight, showed exactly how in the dark Apollo is, since he's being played by both [[BigGood Phoenix]] ''and'' the BigBad. [[IndecisiveDeconstruction All the games that came after this seemed to play it straight, though, so]]...
** It should be noted that this is what makes the games so compelling because the player feels exactly this way as well (and it's the player who calls the shots!).
* Before there was Phoenix, Roger Wilco of ''VideoGame/SpaceQuest'' was this trope on two legs and a mop. Using a jockstrap and a Rubik's cube to distract a monster? Ducking into the orat cave to dodge a Sarien probe droid and watching them blow each other up? He's [[IdiotHero not the sharpest knife in the drawer by anyone's stretch]], but when it comes to improvising a way to save the day (and his ass), he's a freaking grandmaster.
** And yet he's still a janitor, despite saving his home planet and the galaxy several times over. [[NeverLiveItDown You blow up one garbage scow]]...
* Done by Gabe Logan in ''VideoGame/SyphonFilter2'' in the first level, nearly word for word.
* ''Franchise/MassEffect'': Most of Commander Shepard's adventures, due to the fact that s/he has no access to trustworthy intelligence on what is happening and is constantly thrown into situations with no idea what is going on or what s/he is going to do about it. The final mission of ''VideoGame/MassEffect2'' is inherently unplannable, as nobody has ever seen what is on the other side of the Omega-4 Relay and returned to tell the tale. Notably, Shepard is ''trained'' to do this, as a graduate of an elite special operations program that is designed to prepare the trainees to be able to adapt to any situation.
** And then there is this line taken from ''VideoGame/MassEffect3'':
-->'''Defense Councilor''': We need a plan to stop them.
-->'''Commander Shepard''': We fight, or we die. That's the plan.
** Unfortunately for everyone, Aria may be a hell of a badass, but she's a ''terrible'' strategist, meaning that the entirety of the Omega DLC for the third game is an IndyPloy on the part of her and Shepard, after everything falls to pieces.
--->'''Nyreen:''' How did you know you could do that?
--->'''Aria:''' I didn't.
* Adell from ''VideoGame/{{Disgaea 2|CursedMemories}}'' (with a little help from his family) opens the game with the truly ''brilliant'' plan of summoning Overlord Zenon, [[OmnicidalManiac god of all overlords]], into his family's backyard so he, being [[OverratedAndUnderLeveled the mighty level 1 character]] that he is, can beat him up. After the summoning screws up and summons Rozalin, Zenon's daughter instead, Adell is forced into improvising plan after plan for the next six or so chapters as he cluelessly tries to track down Zenon on his own.
* The main character of ''[[VisualNovel/FateStayNight Fate/stay night]]'', Shirou Emiya, relies on this quite often, which tends to cause discomfort among his TrueCompanions. During several "strategy meetings", his allies reprimand him for his usual response of "let's just go and do it".
** Meh, it worked on [[spoiler:[[BigBad Kirei]].]] And Saber tried to do this once (her attempt to attack the magus at the Ryudo Temple in Fate), which lead to [[HypocriticalHumor Shirou calling her on it]].
* The protagonist of ''VisualNovel/{{Tsukihime}}'', Tohno Shiki, despite constantly facing incredibly powerful vampires, never has a plan. Justified in that he really has no idea what he's going up against before he actually faces it. His main means of winning is a combination of inborn talent, inhuman instinct and calmly thinking out the situation DURING the situation. In the end, he's pretty much just making everything up as he goes along. Sometimes his partner at the time (Arcueid, Ciel or Sion usually) try to plan things out ahead of time, but those plans rarely go well. In fact, it's occasionally implied that his VERY EXISTENCE throws a metaphorical wrench in any plans anyone could come up with. This is partially attributed to the fact that no one really knows what Shiki is capable of, including himself. Thus, everyone is constantly surprised by anything he pulls off, and frequently does things in each subsequent game that would have been impossible in a prior one. In other words, in Shiki's case, it's practically impossible to plan ahead.
* In ''VideoGame/{{Runescape}}'', the only way to kill a Vyrewatch is to use a weapon designed for extreme unpredictability - therefore gaining in the sheer power of incompetently planned attacks against a monster who can see coming every competent attack there is. The weapon? ''A [[EpicFlail flail made out of a composite of silver and mithril, with a silver sickle on the tip.]]'' Wow.
** In a later quest where you get a much more reliable set of weapons to fit each combat type. One of the Vyrelords helping you even comments the previous weapon is a complete joke and could be snapped with no effort. So not only it's subverted, but possibly averted too.
* During the first level of ''VideoGame/RatchetAndClankFutureToolsOfDestruction'', the city is under attack, and every attempt Ratchet makes to get where he's going is inevitably blocked by destruction or a large and dangerous robot.
-->'''Clank:''' Ratchet, the Planetary Defence Center is 200 cubits below us. How do you propose we get down?
-->'''Ratchet:''' I don't know. I'm kinda winging it right now.
* From ''Videogame/{{Starcraft}}'', we have Commander Jim Raynor. Despite the fact that he's well respected by Terran and Protross alike for his sound tactical mind, he never really plans anything in advance: he just makes it up as he goes along.
** Mengsk also used to do that during his rebel days, especially in the novels. At one point, his ship, the ''Hyperion'', is confronted by Duke's ''Norad II'' with the usual "prepare to be boarded" speech. Mengsk sets up a siege tank in a hangar bay and opens the doors. He then heads full speed at the ''Norad'', changing course at the last second in order to graze the Confederate's shields (yes, they're equipped with shields). As the ''Hyperion'' is passing the ''Norad'', Mengsk orders the tank to fire. Duke is confused how a battlecruiser can fire a broadside, as all their weapons are forward-mounted (a stupid design, really). When he finds out it was a tank, he just stands for a few minutes with his mouth open, letting Mengsk get away. To note, Mengsk is a student of history, especially the Age Of Sail.
* Nathan Drake, of the ''VideoGame/{{Uncharted}}'' series. Being made of the same cloth as Indiana Jones, no-one is surprised when Nate's idea of a plan is making things up as he goes along.
-->'''Elena''': I sure hope you know what you're doing.
-->'''Nate''': I don't have the faintest idea!
** And even when he ''does'' plan ahead, he does it poorly:
-->'''Elena''': What are you going to do then?\\
'''Nate''': I haven't thought that far ahead!
* ''VideoGame/PrinceOfPersiaTheSandsOfTime'', late in the game. It's appropriate considering the gamer usually doesn't know what they're doing either, latching onto any nearby poles or running across walls that might lead to the next area.
-->'''Farah''': What are you doing?
-->'''Prince''': I don't know, I'm working it out as I go.
* Tidus from ''Videogame/FinalFantasyX'' lives by this, and gets the entire party to go along with it near the end.
* Snow Villiers in ''Videogame/FinalFantasyXIII'' wholly embraces the make-it-up-as-you-go, WhenAllYouHaveIsAHammer style of heroism. It [[BigDamnHeroes works]] [[CrowningMomentOfAwesome sometimes]]; sometimes [[NiceJobBreakingItHero not so much]].
-->'''Snow''': Heroes don't need plans!
** The rest of the group seem to start embracing this mentality (that, or IdiotHero), most notably when they take an action that will ''[[spoiler:destroy the world]]'' with no idea how to stop that from happening beyond the vague notion that "if we have the power to destroy [it], we must have the power to save it". A concept that doesn't really hold true in a lot of situations.
* And as a villainous Franchise/FinalFantasy example we have Kefka Palazzo of ''Videogame/FinalFantasyVI''. His long-term goal: Amass power and abuse it. Stuff he did simply because the opportunity presented itself: Almost everything else... This could be attributed to him being so AxCrazy that his mind cannot formulate detailed plans. Whichever the case, it all worked out pretty friggin' well for him. To the great misfortune of the ones whose lives were ruined, lost, or both.
* ''VideoGame/MetalGearSolid3SnakeEater'' is full of double and triple agents (and a quadruple agent!), who are constantly deceiving each other and furthering their own {{Batman Gambit}}s. Of noticeable exception is [[spoiler:EVA]] who pulls off one of the greatest deceptions in the entire game. [[spoiler:While being on an undercover mission for the Chinese in Russia, she meets an American in the forest who ask her if she is ADAM. Thinking quick she just says that ADAM couldn't make it. The American tells her his name is Snake, so [[AdamAndOrEve she gambles and claims her name to be EVA]]. And he completely buys it, even though she didn't know the password.]]
* VideoGame/MonkeyIsland: Guybrush Threepwood has to do this constantly. He spends much effort in the first game obtaining a way to kill a ghost. Then [[BigBad LeChuck]] knocks him clear across the island, landing him near a root grog vending machine. Guybrush just uses a can of grog instead. Previously, he comes up with a plan to stop [=LeChuck=] from marrying [[LoveInterest Elaine]]. He gets to the church only to find out that she has already escaped. ''VideoGame/TalesOfMonkeyIsland'' is kicked off by Guybrush improvising, which [[GoneHorriblyWrong goes horribly wrong]].
* As with Guybrush, so too with George Stobbart of ''VideoGame/BrokenSword''. Who else can discover an ancient artifact and escape an assassin with half a roll of hand-towels, a sturdy branch, a hand buzzer and a working knowledge of Latin?
** {{Lampshaded}} in the second game; when Nicole asks him what the hell he's doing, George tells he likes to try random stuff in a crisis and see what sticks.
* In ''VideoGame/AssassinsCreedBrotherhood'', after Ezio arrives in Rome and Machiavelli explains the situation to him, he starts walking towards a [[EliteMooks Borgia captain]].
-->'''Machiavelli:''' Do you have some kind of plan?
-->'''Ezio:''' I am improvising.
* Selphie Tilmitt in ''Videogame/FinalFantasyVIII'' pulls a mean Indy Ploy, as she proves when she leads the mission to the Galbadian missile base. She has nothing but a stolen military vehicle and some spare uniforms she happened to find in it, and no plan at all beyond "go in, break everything we can, and blow the sucker sky-high" - and she does.
* The ''VideoGame/TeamFortress2'' video "Meet the Medic" provides a rather spectacular one: The RED Medic invents the Ubercharge system by sticking a strange device onto a baboon heart and implanting it into Heavy (whose original heart ''exploded'' when it had said device attached to it). The two then rush off into battle, and just as Medic is about to pop his very first charge...
-->'''Heavy:''' Doctor! Are you sure this will work?!
-->'''Medic:''' HA HA! I HAVE ''NO'' IDEA!
--> [[spoiler:(''cue Ubercharge and the BLU team getting their asses handed to them'')]]
** This phenomenon happens quite a bit in-game as well, since people are rather unpredictable, you finish just about every round discovering new ways to play. [[{{Metagame}} Unless you win the exact same way you did the last time.]]
* In ''VideoGame/LostHorizon'', the main protagonist likes to operate this way, responding to the suggestion that he hasn't thought things through by saying "It's a lot more fun if you just worry about these things later." Given that the game takes a fair amount of inspiration from ''Franchise/IndianaJones'', this may be a [[InspirationNod deliberate nod]].
* Used several times in all three of the ''VideoGame/MaxPayne'' games. Max often finds himself wandering into a fortified complex full of gun-toting goons armed only with his trusty beretta and a handful of painkillers and no plan beyond 'kill the bad guys'. Somewhat subverted in that Max doesn't really care if he gets gunned down in a blaze of glory or not, since he's a notorious ''DeathSeeker''.
* ''VideoGame/ResidentEvil6'': In his third chapter, Jake decides he's TiredOfRunning and decides to take down the attack helicopter that's hounding him and Chris's team, but then admits to Sherry that he's making it up as he goes and has no idea ''how'' he's going to pull it off. Fortunately, Sherry just happens to have some explosive rounds with her to even the odds.
* ''VideoGame/BioshockInfinite''. This is Booker [=DeWitt=]'s standard procedure throughout the entire game. He's constantly jumping out of the frying pan into the fire, having to improvise in order to find Elizabeth, catch up to her again when she runs off and rescue her when she's captured. Justified because he has false memories of his past and a severe lack of useful information from his employers who do know what's going on - the Luteces. {{Lampshaded}} right after he [[spoiler:kills Comstock]]: when Elizabeth asks him how they're going to destroy the [[spoiler:Tower and the Siphon]] he says "I don't know, but I'll think of something on the way."
* A villainous example in ''VideoGame/CommandAndConquerTiberiumWars''. At first, it appears as if [[spoiler:the Scrin]] are conducting a very well-organized, meticulously planned attack when they show up. But then when you play the third campaign of the game, it turns out that ''they didn't have a plan'' [[spoiler:due to the fact that Kane tricked them into arriving almost a century too early, and their force was not equipped for an all-out war.]] Everything they do is simply a desperate attempt at a DelayingAction, turning a lot of their non-combat equipment into {{Improvised Weapon}}s, and generally really hoping their enemies don't catch on to the fact that they're actually a lot less powerful than they seem.
** A larger example, as revealed in ''VideoGame/CommandAndConquerTiberianTwilight'', is [[spoiler:Kane's ultimate goal of the series. It turned out that all he was trying to do was find some way to get off of Earth, and that every Tiberium War he started was more or less an IndyPloy.]] [[FanDislikedExplanation Fans did not take this well at all.]]
* ''VideoGame/MinecraftStoryMode'': While they always have a general idea of what they're trying to do, the unpredictable behavior of [[spoiler:both Ivor and the Wither Storm]] keeps forcing Jesse and the rest of the team to improvise during emergencies. Lukas isn't too pleased about this.
--> '''Lukas:''' We need a plan... and not the usual "we'll-come-up-with-a-plan-when-we-have-to-[[SuddenlyShouting OH-WAIT-NOW-WE-HAVE-TO]]" kind.
* In ''Franchise/TheElderScrolls'', this is a common trait for heroes of the [[CatFolk Khajiit]] race, to the point that they even have [[OddJobGods a god for this concept]], Baan Dar. He is commonly attributed with "the genius which lends itself to the creation of last-minute plans to foil the machinations of the Khajiit's foes."

[[folder:Web Comics]]
* ''Webcomic/{{Narbonic}}'''s Helen Narbon is an avowed fan of this approach: "It's times like these I almost question my usual strategy of doing whatever dumb thing pops into my head."
** Subverted later on when she implies that [[ChessMaster pretty much everything that's happened for a little over half the comic all part of her plan]]. (Asked by Dave whether she is a mistress of GambitRoulette or just does whatever the voices in her head say, she questions whether these are even different things.)
* This trope is precisely why Rumisiel gets [[CrowningMomentOfAwesome Crowning Moments Of Awesome]] in ''Webcomic/{{Misfile}}''. Even when his schemes work there is still an element of WhatWereYouThinking.
* Gil [[http://www.girlgeniusonline.com/comic.php?date=20090223 claims to be doing this]] in ''Webcomic/GirlGenius''. Apparently rendered plausible by past behavior.
* ''Webcomic/{{Wigu}}'':
-->'''Sheriff Pony''': Topato has never lost a battle, and prefers to act without planning in order to create a "chaos factor" so that the battle's inevitable victory may also yield some unexpected, interesting side-results.
* Casper of ''Webcomic/{{Darken}}'' is good with these. Highlighted even further in his solo chapter with the Yuan-Ti Jade, which reads like a swords-and-sorcery fantasy Indy comic - complete with doomsday device!
* ''Webcomic/{{Lackadaisy}}'':
-->'''Rocky''': ''Always'' be prepared to improvise, Freckle. That's rule number one for jazz players and vigilantes alike.
** Are you sure this is, uh--
*** [[http://www.lackadaisycats.com/comic.php?comicid=19 Are you questioning his logic?]]
* In ''Webcomic/SchlockMercenary'', when amnesiac mini-Schlock [[http://www.schlockmercenary.com/d/20050529.html disposes of Pranger's materiel]], Kevyn grabs the initiative and takes out an enemy tank. [[http://www.schlockmercenary.com/d/20050531.html His plans run out at that point]], not to mention it makes a proper mess of his allies' own plans.
-->''Plan E vanishes in a puff of unpredictability, and colonel Pranger finds himself in the [[ThisIsGonnaSuck unenviable position]] of having to orchestrate twenty-five minutes or more of "winging it"''
** This is not unusual, and in fact it's unusual for a plan to '''not''' devolve into one sooner or later (often within minutes). Mercenary work and careful planning don't mesh well past the first shots fired, and the Toughs' tendency to barge into others' plans without even knowing it makes sure ''everyone'' gets to try and improvise their way out of the newest clusterfuck.
* This is Mega Man's and Quint's modus operandi in ''Webcomic/MSPaintMasterpieces''. The fact that Mega Man broke down all of his carefully constructed and thought-out schemes with just making it up as he goes along is the straw that breaks Dr. Wily's back. Formerly provided the page quote:
--> '''Quint:''' Ha, Loser. A true tactician doesn't know WHAT the hell he's doing until he's halfway done with it.
* In ''Webcomic/TheInexplicableAdventuresOfBob,'' Bob's gift for doing this is not only why he's still alive, but why the world hasn't ended horribly and repeatedly.
* Meta example with ''Webcomic/{{Homestuck}}'' - Creator/AndrewHussie had a basic idea for the characters and plot when he began it, but most of what you see and read was made up along the way. ''Webcomic/ProblemSleuth'' takes this even further, having had only its setting and main character designed in advance, and the rest made up by Hussie and the readers.
** In-universe example with [[TheLancer Dave's]] approach to handling his TimeMaster powers:
--->'''TG: the thing with time travel is'''\\
'''TG: you cant overthink it'''\\
'''TG: just roll with it and see what happens'''
* Xeus from ''Webcomic/TheBeastLegion'' makes such a move when he takes on a plant mongrel in [[http://www.thebeastlegion.com/issue-03-page-37surprise-counter-attack/ this page]].
* In ''Webcomic/{{Freefall}}'', this is Sam Starfall's stock in trade. After all, [[http://freefall.purrsia.com/ "Improvise is one of the few battle plans that survives contact with the enemy."]]
* Parson from ''Webcomic/{{Erfworld}}'' is a grand master of the Indy Ploy. He was summoned to be the perfect warlord and save an army outnumbered a zillion to one and losing badly. What he had accomplished up to that point had been impressive but he had not proven infallible. When his officers start to question him, he directly [[http://www.erfworld.com/book-1-archive/?px=%2F124.jpg explains the concept of the Indy Ploy to his troops]]. As this speech happened two "volumes" ago in-comic, it isn't much of a spoiler that he finds a way.
* In ''Webcomic/CommanderKitty'', [[http://www.commanderkitty.com/2011/01/16/mittens-has-another-cunning-plan/ the newly-confident Mittens is happy to get the "I'm sure it'll work out" part of his plan out of the way early on.]]
* Corey/Luke in ''Webcomic/DarthsAndDroids'' has no idea what use a harpoon and tow cable will be in a [[http://www.darthsanddroids.net/episodes/0968.html battle against giant walking machines]]. (Note that [[ActorAllusion Han Solo approves.]])
* Quant from ''Webcomic/TowerOfGod'' found himself in a very sticky situation: Ho was holding Rachel hostage and tried to kill her before, Parakewl and Mauchi were trying to profit from this and pierce him with their lances and Baam was blackmailed into fighting him. What to do? Hit the little genius with a paralyzing technique and tell him to copy it and use it on Ho, so that he'd have the courage to jump in to save Rachel, while Quant takes care of the others, of course. He never expected it to work, but who cares?
* This becomes Allison's signature style in ''Webcomic/KillSixBillionDemons'', thanks in large part to being TrappedInAnotherWorld, the unwilling owner of a CosmicKeystone, and possibly the heiress to the Throne of the Multiverse. Best demonstrated when she offhandedly decides to make a pact with a devil to infiltrate a GodEmperor RealityWarper's flying palace to find her boyfriend and deals with the fallout as it comes.
--> ''"I'm drunk as hell and I have '''no''' idea what I'm doing."''
* ''Webcomic/TheOrderOfTheStick'''s reliance on this is lampshaded in [[http://www.giantitp.com/comics/oots1108.html this strip]]:
--> '''Hilgya''': That's it? ''That's'' your plan?
--> '''Roy''': I hear what you're saying, but you have to understand it's been a shockingly effective strategy for us in the past.

[[folder:Web Original]]
* In ''WebVideo/DoorMonster'''s [[https://www.youtube.com/watch?v=Uam0KMyZh2E&index=3&list=PL0u5ZHidq4X4QhFAX9FzSiYJLRen74sLF The Guards Themselves]], Noam and the crew [[spoiler:show up to free their comrades from jail, but have no plan for actually getting them out]]. [[LampshadeHanging Lampshaded]] by Emma.
--> '''Emma''': Oh, you're unprepared? Oh my god, who could have seen that coming?
* The Brotherhood of the Poofy Pants in ''Obleeq'', from WebVideo/NatOneProductions rely heavily on making it up as they go along. As their Spiritual Advisor [[CrazyHomelessPeople Grabpot Thundergust]] would say, "Murradin will provide."
* In the Literature/WhateleyUniverse, most of the fights that Team Kimba get into fall into this trope, since so far they haven't planned out any of the major confrontations that have dropped onto them. Chaka lives by this trope, when she's not actually thinking things through enough to be TheChessmaster.
* [[Machinima/LeeroyJenkinsVideo LEEEEROY JENKINS!!!]] is an example of the 'WhatWereYouThinking' variety. While the video was staged, along with Leeroy's blinding incompetence, the creators said it was based on a real (although presumably less over-the-top) event.
* Unlike many practitioners of the Indy Ploy, Skitter, protagonist of ''Literature/{{Worm}}'', prefers to go into battle with a solid plan. When that's not possible, or when unexpected circumstances derail the plan, she has a gift for inventing effective tactics on the fly using anything and everything she can get her hands (or [[TheMinionMaster insects]]) on.
* Dr. Kondraki of the ''Wiki/SCPFoundation'' loves this. Some of the steps of his [[http://scp-wiki.wikidot.com/duke-till-dawn plan to terminate SCP-083]] were "Wing It," "Make Something Up," "Cross That Bridge When I Come To It," and "Put My Head Between My Knees And Kiss My Ass Goodbye".
** Taken [[UpToEleven up to eleven]] during the brief online SCP-themed roleplay channel, the rules of which were crafted by both Kondraki and the even more infamous Fishmonger. The game system they devised was actually designed to be imbalanced ''on purpose'', and players were encouraged to make characters with absolutely ludicrous stats. Indy ploys were a normal function of gameplay; arguably there was no point where the resultant campaign was actually ''on'' [[OffTheRails the rails]].
* In ''Roleplay/STOForumVersusThreadRP'' the players are frequently reduced to this, although Eleya does this more than most. Before executing one of her wackier plans her player refers to her as going into "Crazy Improvising Bajoran B***h" mode. The end result of that particular improvisation was [[spoiler:her using the Iconian computer virus to singlehandedly destroy a Borg probe and a tactical cube and render the entire system impregnable to the Borg. The DM gave up and {{Dropped a Bridge on|Him}} the Borg Queen offscreen.]]

[[folder:Western Animation]]
* Prince Zuko from ''WesternAnimation/AvatarTheLastAirbender'' [[WhatWereYouThinking never seems to think things through]] and frequently [[TheWoobie suffers]] for it. Iroh calls him out on it because his success rate is much worse than that of Indiana Jones.
** "The Boiling Rock" actually has something of a running conversation between [[spoiler:Zuko and Sokka]] throughout the episode on when to think things out, and when to just go with this. They decide to plan what they can, and improvise when they need to.
* In early ''WesternAnimation/{{Ben 10}}'', the titular character expressed "Who needs a plan when you've got the watch!" thought process, often selecting the alien forms that possessed the most brute strength or coolest powers. In "Hunted", a fake bounty hunter calls Ben out on this primitive strategy, and since then, he has been more creative with the Omnitrix. Well, more or less.
** Also of note is that although Ben had access to numerous transformations with vast strategic value, such as a [[ImplacableMan resilliant]] [[PlayingWithFire pyrokinetic]] with [[NotQuiteFlight pseudo-flight capabilities]] and a [[FrickinLaserBeams laser-equipped]], [[{{Technopath}} technopathic]], [[{{Nanobots}} nanobot]] construct with [[BlobMonster blob]]-esque attributes, Ben's most-used form in the series by far is the [[MultiArmedAndDangerous four-armed]] MightyGlacier whose selling point is SuperStrength (despite half of his other forms having superhuman strength to begin with).
** The Omnitrix often disagreed with Ben's choices in the first series, necessitating Ben having to think up a plan other than 'hit it till it stops moving' on the fly. ''Especially'' if the Omnitrix decided to turn him into [[ShorterMeansSmarter Grey Matter]].
* Most of the time, ''WesternAnimation/TheFairlyOddParents'' plays this trope straight, with Timmy having to think on the fly to fix whatever he's just screwed up.
* ''WesternAnimation/KimPossible'': Ron's usual MO, especially when faced with the controls of a DoomsdayDevice:
-->'''Ron''': Rufus, this is a precision instrument, incredibly complex.
-->'''Ron''': Better mess with everything.
* ''WesternAnimation/SpongeBobSquarePants'': Although Plankton is usually shown to have elaborate schemes, he does hang a {{Lampshade}} on this concept on at least one occasion.
-->'''Plankton''': Give me the secret formula OR ELSE!
-->'''Krabs''': Or else what?
-->'''Plankton''': Uh, I don't know. I didn't think I'd get this far.
* A common theme in early episodes of ''WesternAnimation/{{Reboot}}'' was that Bob never thought more than 6 nanoseconds ahead, and Dot never did anything without careful forethought. Naturally, this led to friction as the two competed to prove which approach was best, while events provided a subtle Aesop that a balance between the two was really the best approach.
* A particularly memorable conversation on ''WesternAnimation/BuzzLightyearOfStarCommand'', when Mira is hitching a ride inside Buzz's head:
-->'''Mira''': What now?
-->'''Buzz''': Don't worry. I have a plan.
-->'''Mira''': Hey, I am inside your head, and I can see you don't have a plan!
* Used in the ''WesternAnimation/{{MASK}}'' racing episode ''Battle of the Giants'' for no particular reason.
-->'''Trakker''': [The plan is] perfect in its simplicity, and the one plan [VENOM] will never guess. The No-Plan Plan!
-->'''Lefleur''': No plan?
-->'''Trakker''': VENOM can't figure out what we're doing if we don't know ourselves.
* Finn {{Lampshades}} this in an episode of ''WesternAnimation/AdventureTime'' when he manages to get through a door of the Ice King's fortress after mentioning having a plan: "Nah, that wasn't my plan. I just got lucky."
* The ''WesternAnimation/YoungJustice'' team learn this as their first lesson from Franchise/{{Batman}}: when the plan goes south, good heroes make do.
* Used and {{Lampshaded}} in the ''WesternAnimation/PhineasAndFerb'' episode "Meapless in Seattle".
--> '''Candace''': So, uh, do we have a plan, or are we just gonna go all willy-nilly and barge into the bad, scary place?
--> '''Phineas''': You know, willy-nilly barging ''is'' a plan of sorts.
--> '''Candace''': *[[OhCrap looks terrified]]*
* ''WesternAnimation/KungFuPandaLegendsOfAwesomeness''. Po's tendency to do this is spoofed in "Chain Reaction".
-->'''Tigress:''' ''(as they're falling to their deaths)'' BAD IDEA! BAD IDEA!
-->'''Po:''' [[ItSeemedLikeAGoodIdeaAtTheTime NO KIDDING!]]
* Rick of ''WesternAnimation/RickAndMorty'' frequently improvises plans on the spot, with most of them succeeding thanks to his genius.
** Nowhere is this more apparent that the season 3 premiere. Rick had turned himself in to the Federation in order to take it down from the prison he was in, and uses the machine being used to interrogate him to transfer his mind into the body of a Federation agent. His original plan was just to get Level 9 access, but other Ricks come in to kill him. So, for his new plan, he transfers his mind to one of the other Ricks, goes back to the Citadel of Ricks, then transfers it to a higher ranked Rick, goes to a room, and teleports the entire citadel back to the prison he was originally in, thus {{telefrag}}ging both facilities at once and breaking into the level he wanted to get into in the first place.
---> '''Rick''': And ''that'' is how you get Level 9 access without a password.


[[folder:Real Life]]
* The founding father of game theory (no, not [[WebVideo/GameTheory that one]]), John Von Neumann, famously said that a random strategy is the only strategy that cannot be guaranteed to be beaten by some other strategy. So, if you are going up against someone who is smarter, with more resources, and whose likelihood of understanding your strategy (if you had one) and replying with a better one is 100%, your only option for a non-zero chance of success is an Indy Ploy.
** This level has been reached with the best chess playing programs. They can still be beaten by human grand masters, but by far the most effective opening strategy for doing so is to make a random opening that makes no sense whatsoever. There's no way that the computer isn't going to know any coherent opening game and counter it. (Computers can use brute force to compute every possible course many moves into the future, so there's no way for a human, with much more limited ability to examine possible future states of the game, to compete with that approach. Random play allows a human to, sometimes, reach a place in the phase space of possible games where they have enough of an advantage to win.)
* As the old adage goes, the most dangerous opponent is a complete newbie because you don't know what he's going to do.
* ''Webcomic/BobAndGeorge'': the author freely admits that a large portion of the comic is done on a day-to-day basis, so the ''creation of the comic'' is more or less a RealLife Indy Ploy.
** Not entirely uncommon among serial authors. Often, one will have the big events plotted out (character deaths, villain appearances), but will come up with the intervening comics as he or she makes them.
** Disgruntled Ferret of Webcomic/MSPaintMasterpieces (whose comic is posted on the Bob and George website) had a story all planned out, but lost some sprite sheets he prepared. He was forced to improvise and change the whole ending to his version of events for the second Megaman game. It worked out surprisingly well.
* A few real books were written this way (the author just making it up as he goes along in one draft with no revisions), such as the novel ''Hawaii''.
* As well as the entire ''Literature/LordOfTheRings''. Tolkien had a vague idea of the ending, but he had no idea how to get there until he got there. Every big event, from beginning to end, was designed while it was being written. The only scene he even tried to write ahead of time was the climactic scene inside Mt. Doom, and the final one was still written only when the story got to it.
* Creator/RumikoTakahashi never really plans ahead. She just comes up with the story by a chapter by chapter basis. In fact, this is ''very'' common among mangaka who publish works on a weekly basis, due to the small window of time they have to come up with anything. One of the more extreme examples out there is Creator/AkiraToriyama, who came up with his plots ''[[WritingByTheSeatOfYourPants while he was drawing each chapter]]''.
* Writer Creator/SidFleischman once quipped, "I'm anxious to get to my desk each morning to find out what's going to happen."
* This was actually how American football's signature feature, the forward pass, came into being. In the early 20th Century, many colleges were considering abandoning Walter Camp's football code in favor of rugby. In a game between the University of North Carolina and the University of Georgia, a punter threw the ball towards a teammate downfield while trying to avoid getting creamed by an oncoming rush. The receiver made a 70-yard touchdown (including the pass) to win the game for the UNC Tarheels, 7-0. This was witnessed by one Johnny Heisman, who related the story to Camp. Seeing a way to open up the game and make it more exciting to fans, he agreed to legalize the forward pass. Along with the abolition of the Flying Wedge Formation and the adoption of heavy protective padding, changes designed to fix the ''other'' problem of players being killed and crippled, the forward pass is credited with saving the game of American football.
* The Portuguese actually have a ''word'' for this: [[http://www.cracked.com/article_17251_the-10-coolest-foreign-words-english-language-needs_p2.html Desenrascanço.]]
* The Duke of Wellington said of the French generals he defeated: "They planned their campaigns just as you might make a splendid set of harnesses. It looks very well; and answers very well; until it gets broken; and then you are done for. Now I made my campaigns of ropes. If anything went wrong, I tied a knot and went on."
* Mike Tyson basically said the same thing, but more succinct: "Everyone has a plan til they get hit in the face."
* A celebrated military mind of the 19th century, German Generalfeldmarschall [[http://en.wikipedia.org/wiki/Helmuth_von_Moltke_the_Elder Hulmuth von Moltke the Elder]], said: "No plan of operations extends with certainty beyond the first encounter with the enemy's main strength." This is usually paraphrased as "no plan survives contact with the enemy." Even if you ''do'' have a plan, once things get started, it can only help so much.
* T.E. Lawrence (Lawrence of Arabia) repeatedly states in his memoirs that, being an archaeologist rather than a military man, he knew very little about how to fight a revolution. Therefore, in the beginning of his time with the Arab revolt he was making up a plan as he went. It was not until several months into the campaign, when he was laid up with a case of dysentery, that he had a chance to analyze the goals and methods of the campaign he had been helping to lead! He ended up almost single-handedly inventing modern guerilla warfare.
* Just about any space mission looks a lot like this. When things go wrong (and things always go wrong to a greater or lesser degree), the success or failure of the mission, and often the lives of the astronauts, depend on the resourcefulness and cleverness of the astronauts and MissionControl. The Apollo 11 and 13 missions both had several examples of this. In large part this is because of NASA's tendency to be CrazyPrepared: if something happens that isn't covered by "flip to page 173 of the LM Operator's Handbook and follow procedure 6", it's ''really'' out there.
** The mission in between, Apollo 12, was ''struck by lightning'' (''twice!'') during launch and was saved from having to abort only because flight controller [[https://en.wikipedia.org/wiki/John_Aaron John Aaron]] (the original [[Film/{{Apollo13}} "steely-eyed missile man"]]) had seen similarly garbled flight telemetry during an earlier simulation and remembered what had worked to fix it. He made the call "try SCE to aux", instructing the astronauts to flip a switch so obscure that only Lunar Module Pilot [[https://en.wikipedia.org/wiki/Alan_Bean Alan Bean]] (who'd been in the same sim a ''year'' prior) knew where it was on the console.
* UsefulNotes/WorldWarII: On June 6th, 1944, Operation Overlord became this trope writ [=LARGE=] even before the first troops hit the beaches. To the tune of hundreds of thousands of US and Allied troops.
** The [[ItsRainingMen US 82nd and 101st Airborne]] Divisions were especially good at this trope. The whole role of paratroopers is to be cut off behind enemy lines with limited supplies and often no contact with command at all. You complete your mission and hope to god the main friendly force reaches you before you run out of ideas/bullets/people.
* Any teacher in a given children´s school may have to plan like this. It is always ''something'' going on, derailing the education.
* Your own life. It's always a running cycle of ploys.
