->''"That's how it always begins. Very small."''
-->-- '''Egg Shen''', ''Film/BigTroubleInLittleChina''

Someone investigates a minor crime, or possibly something as major as murder, but finds something much bigger going on behind it. The first crime might be part of a RevealingCoverup, or it might be just a RedHerring; it can also be both the cause and effect of CrimeAfterCrime. This is extremely common in crime fighting action films where the plot is more about building up a lead in from normal life and confronting the big secret; in other fiction there might be all manner of twists, turns and dead ends before it all links up. This is a staple of the detective variety of Film Noir.

Some of the more complex {{Evil Plan}}s may stretch from the most trifling crimes to the mind-bogglingly evil in a [[GambitRoulette mind-bogglingly complex manner.]]

Sometimes the AntiVillain is [[TheReveal revealed]] to be quite heinous; in other cases the AntiVillain teams up with the {{heroes}} to fight the BigBad.

Works in which several different crimes are committed (e.g. a PoliceProcedural TV series) sometimes follow the pattern that ''every'' Minor Crime reveals a Major Plot - the main characters can't investigate any crime, big or small, without stumbling upon an EvilPlan involving [[LoadsAndLoadsOfCharacters several different people]] and six- or seven-digit sums of money. This is largely an [[AcceptableBreaksFromReality Acceptable Break From Reality]]: of course, in RealLife, thousands of crimes are committed each day without any sort of plan or conspiracy behind them – burglars sneak into homes to steal some small cash, people are killed when petty arguments get out of hand, [[ArsonMurderAndJaywalking dastardly villains cross streets in illegal ways to get to the other side faster]] – but it makes for a more interesting story to have your master detectives slowly uncover the villainous plot of a DiabolicalMastermind than to have them book [[BitPartBadGuys random mugger after random mugger]].

Contrast InfractionDistraction, where a minor crime is committed to conceal a greater one.

TruthInTelevision. RealLife professional criminals will bend over backwards to make sure they don't trip up over something minor, because it's happened before. The best way to avoid capture is to not attract attention – at all. However, many criminals do not maintain professional standards and are caught for things like not paying fare on the subway, or expired license plates.

As this is a trope about plots, '''many of the examples will contain spoilers'''. You have been warned. When it's the ''criminal'' who only intended to commit a minor crime, it's UnintentionallyNotoriousCrime.

Not to be confused with WantedMeter.

* Subverted in ''Film/StrangeDays'': While investigating the murder of a rapper and a prostitute, the hero learns that the murders are related to a massive police conspiracy involving "death squads."

This ring apparently was active all throughout the [=NYPD=], going as far up as the District Attorney.
* ''Film/{{Showtime}}'': a drug bust leads to the discovery of a dangerous new weapon that is about to hit the streets. Admittedly, it's difficult to call a drug deal operation a "minor crime", but still. Also, the BigBad was ''extremely'' upset that the drug dealer used one of his prototype guns, tipping off the cops.
* A variation in ''Film/SuperTroopers''. Two crimes end up hinting at the major plot, but neither can be considered minor. A routine traffic stop reveals a major marijuana smuggling operation through Vermont. A body found in a Winnebago ends up revealing that [[spoiler:the local Spurbury police are running protection for the Canadian smugglers]]. The latter is subverted in that the state troopers don't really figure it out until [[spoiler:Ursula]] pretty much has to show them what's going on. They do get credit for apprehending all the culprits, though.

* ''Origin Literature/InDeath'': Murder of "saintly" doctor → massive decades-old illegal human-cloning and people-made-to-order operation.
* The UsefulNotes/ColdWar thriller ''An H-Bomb for Alice'' by Ian Stewart. A detective investigates the apparent suicide of the Australian Minister of Aboriginal Affairs.

It turns out the Soviet Union is planning to invade China, and a hidden strike force is waiting to seize the US surveillance station at Pine Gap which they fear will provide prior warning of the attack. The strike force was operating under the cover of a hippy colony that would have been evicted from Aboriginal land if the bill had been passed.
* Franchise/SherlockHolmes stories had a lot of this.

*** Vimes actually [[LampshadeHanging lampshades]] this while talking with another character, referencing a case wherein a man had killed his dog, with Lord Vetinari ordering Vimes to search the man's house, stating that "where one finds little crimes, one often finds larger crimes." Vimes confirms to the other character that they did find larger crimes connected to the dog-killer.

* ''[[Literature/HonorHarrington On Basilisk Station]]'': routine policing to stop smuggling, and the murder of several local cops leads to the discovery of a plot for invasion. Amusingly played with in that the people doing the plotting try to call the invasion ''off'' and would have been able to do it unmolested if their plot hadn't been so revealed.
* ''Literature/HalfMoonInvestigations'' has the young detective investigating a series of sabotaging attacks on various members of the community, but in the process he discovers that several of the events were carried out by a separate conspiracy. YMMV as to which conspiracy was the major or minor, but the fact that the one accidentally discovered was being carried out by ten-year-old girls with all the efficiency of an adult...
* The ''Literature/RepairmanJack'' novels by F. Paul Wilson often start with Jack being asked to solve a small mystery, such as a missing person or a robbery. This mystery invariably turns out to be related in some way to the bigger 'Adversary Cycle' arc that spans the whole series.

** ''Point Blanc'': [[MakeItLookLikeAnAccident "accidental" deaths]] of a New York multibillionaire and an ex-KGB general → [[spoiler:an apartheid scientist replacing the children of sixteen powerful men around the world with teenage clones of himself.]]
** ''Skeleton Key'': sale of uranium to a former Russian general and death of the two men who delivered it → [[spoiler:plan by the general to detonate a nuclear bomb among a fleet of decaying nuclear submarines, contaminating most of Europe, seizing power in Russia, and reinstating Soviet communism.]]
** ''Eagle Strike'': attempted assassination of journalist Edward Pleasure → [[spoiler:attempt to wipe out drugs by dropping 25 American nuclear missiles on worldwide drug sources.]]
** ''Ark Angel'': attempted kidnapping of Paul Drevin → [[spoiler:plan to drop the Ark Angel hotel from outer space onto Washington, D.C.]]
** ''Snakehead'': two deaths of ASIS agents infiltrating a snakehead and the theft of a bomb prototype → plot to wipe out an island conference aiming at ending world poverty [[spoiler:by creating a tsunami that will also wipe out most of western Australia.]]
** ''Crocodile Tears'': investigation into an accountant at a bio-research facility → [[spoiler:the BigBad's plot to create a famine in Africa via poisoned wheat, then claim millions of dollars through his charity.]]
** ''Scorpia Rising'': This one's complicated. The murder of Levi Kroll plus a shooting at Alex's school → [[spoiler:a plot to assassinate the American secretary of state and frame Alex (and by extension the British government) for the crime]], thereby giving Scorpia leverage to force the British government to return the [[https://en.wikipedia.org/wiki/Elgin_Marbles Elgin Marbles]] to Greece. Then at the end, it's revealed that [[spoiler:the school shooting had nothing to do with Scorpia's plot. That was masterminded by Alan Blunt so Alex would think he was in danger and agree to go to Cairo for [=MI6=].]]
* In the Literature/TanteiTeamKZJikenNote series, Aya {{discussed|trope}} this trope with Kuroki during ''The Backyard Knows'', expressing some disappointment that the crime involved in the arc was indeed minor, performed by a perennial small-time criminal without more apparent complexities. [[spoiler:But the story does go that way, although still downplayed: it lead to a case of museum theft which causes the loss of some expensive butterfly specimens.]]
* In ''Literature/TheYiddishPolicemensUnion'', a man's murder (while stretching the limits of ''minor'' crime) eventually reveals [[spoiler:a plot by conservative Jews in collaboration with right-wing America to overthrow Palestine (which in this AlternateUniverse is still a widely recognized sovereign state, [[{{UsefulNotes/Israel}} Israel]] only having existed in the modern world for a few months) by blowing up the al-Aqsa mosque, the third-holiest site in Islam]], which is dramatically worse.
* In ''Literature/TheCaseOfTheToxicSpellDump'', a routine EPA investigation into a potential leak at an industrial waste dump uncovers a conspiracy to revive a GodOfEvil.

[[folder: Live Action TV ]]
* ''Series/{{Castle}}'': This appears to have been the case for [[spoiler: Beckett's mother's murder]]. Decade-old murder of a lawyer → [[spoiler: wide-ranging corruption and conspiracy, the full extent of which has yet to be revealed.]]
** Also, murder of a taxi driver → [[spoiler: plot to detonate a dirty bomb in New York.]]
** But subverted with a second season episode where vehicular homicide of a bike messenger → terrorist attack. The attack idea came out of the sender being listed S. Nadal Matar, who turns out to be on the terror watch list. ESU breaks down a door to discover an old lady named Sally ''Neidermeyer''.
---> '''Castle:''' Our bad.
** Also subverted in "The Lives of Others": [[RearWindowInvestigation evidence of foul play and a possible murder in the apartment across the street]] → [[spoiler: birthday party for Castle]]
* ''Series/StateOfPlay'' starts off with a murder, an affair and a suicide which are all investigated by the newspaper who find [[spoiler: that they are all related to a much larger government conspiracy]].
* Several ''Series/{{Leverage}}'' episodes do this, albeit on a smaller scale than a lot of the examples:
** "The Homecoming Job". Coverup of a friendly fire investigation → multi-billion-dollar money-laundering scheme.
** "The Snow Job". Negligent home contracting job → nationwide foreclosure-related fraud.
** "The Stork Job". Spanish Prisoner scam with orphans → weapons smuggling.
** "The Gone-Fishin' Job". People being scammed by fake IRS agents → anti-government militia planning a terrorist attack.
** The canon novel "The Con Job". Dealing with a forger stealing original work from aging comic artists → Preventing a Japanese real estate developer/crime boss from ''killing everyone at Comic-Con with a car bomb'' so he can set it up in his own hotel(!).
*** There ''are'' some ''big'' ones from Season 3 onwards, however;
** "The Inside Job". A theft from an agricultural company → ''plot to cause a global famine so the company can profit from its monopoly on blight-resistant wheat.''
** "The Double-Blind Job". Accidentally foiled kidnapping/assassination → plot to knowingly release toxic drug nationwide, killing anywhere from thousands to ''millions'', earning the Evil Drug Company '''billions''' for a 15% fine.
-->'''EDC CEO''': ''That's like tipping your waiter. "Thank you very much for taking our drugs. Here's a little something for your family."''
** "The Big Bang Job". Investigation of international criminal → ''plot to destroy Washington DC with a prototype EMP city-buster.''
** "The Long Goodbye Job". Stealing orphan drugs to treat rare terminal illnesses → ''stealing proof that international law enforcement let international criminals steal '''one-third of the entire world's wealth''' during the 2007/2008 financial crisis.''
* ''Series/{{Weeds}}'' subverts the hell out of this early in the third season. The second season CliffHanger ends with Silas arrested for petty vandalism with a trunk full of marijuana [[spoiler: but Celia drives away in his car before the cop sees it]], and a few episodes later a DEA agent shows up at the Botwins' door while they're bagging product [[spoiler: but never gets in the door so he doesn't notice it]].
** Also played straight at the end of the third season: [[spoiler: stolen cross → new grow house]].
* ''Series/TwinPeaks'': The murder of a teenage girl → otherdimensional demonic conspiracy (to confuse the audience).
* Not a few ''Franchise/LawAndOrder'' episodes start with some minor problem, such investigating a noise in an alley, lead to a dead body (or two), and often then into something much, much worse, often involving murder, prostitution, and/or financial skulduggery. Fairly common on ''Series/LawAndOrderSpecialVictimsUnit'', but turns up on the other variations as well.
** An early episode has the murder of an off-duty officer actually turn out to be a suicide, evidence of which was hidden by the officer's fellow cops so his family wouldn't lose his pension. It ''then'' leads to an investigation of why an all-accounts honest cop would kill himself, and it uncovers a history of childhood sexual abuse by his priest, and he wasn't the only victim.
** One episode opened with a dispatching error sending Briscoe and Curtis to what they think is a murder, but turns out to be the discovery of a dead horse instead. Much to their frustration, their Lieutenant tells them to look into it anyway (there being no other pressing cases at the time) and their investigation eventually leads to a con artist who may have murdered his millionaire patron.
** In another, the burglary of a safety-box depository uncovers wads of cash being stored there that date to an armed robbery/homicide from the 1960s.
** This can sometimes be done to a ridiculously huge degree. One episode involves finding the body of what looks like a hobo in a stairwell, and ends up with a UN trial involving the Russian mafia.
** The 14th season finale of ''SVU'' involves the arrest of a man for indecent exposure; he eventually turns out to have perpetrated multiple sex crimes, up to and including sexual torture and murder, in several different states, but has managed to [[KarmaHoudini escape conviction]] in every case.
* ''Series/TheWire'': Season Two: Warfie with suspicious amounts of money buys a stained window for a church → bulk smuggling of drugs, prostitutes and goods; multiple ethnic gangs, murders agogo. Hilariously, or depressingly, the guy who tipped the unit off to the church window doesn't give a shit about the vast criminal network they uncovered, he just wants his slobby dockworker nemesis to ''pay big-time'', and he'll gladly fuck his own people over if it will ensure that it happens.
* This has happened frequently on ''Series/CSIMiami''.
* This seems to be the point of the BuddyCopShow, ''Series/TheGoodGuys''. An old NobleBigotWithABadge CowboyCop [[OddCouple is paired with a young]] ByTheBookCop and sent to investigate minor crimes (vandalism, shoplifting, etc.) to [[ReassignmentBackfire keep them out of trouble, but the duo almost always stumble across something much bigger]] (drug smugglers, car theft ring, etc.)
* Pretty much every MythArc episode of ''Series/TheXFiles'', and several Monster of the Week ones as well.
* ''Series/TheShadowLine'': The death of a drug baron → [[spoiler:A GovernmentConspiracy using drug money to fund police pensions.]]
* ''Series/CriminalMinds'': DEA raid on a suspected meth lab → an impending terrorist attack using nerve gas.
* ''Series/StarskyAndHutch'' does this almost every episode.
* ''Series/{{Bones}}:'' A recovered skull → A cannibalistic serial killer [[spoiler:who ends up recruiting Zack as his apprentice.]]
* Happened on occasion in ''Series/DueSouth''. One notable example was Frasier and Vecchio stopping to ticket a man who had parked in a fire lane, only to discover the guy's trunk was full of illegal firearms.
* In a few ''Series/{{Monk}}'' episodes:
** In "Mr. Monk and the Class Reunion," the murder of a retired college nurse leads Monk to discover a murder plot involving Trudy's freshman roommate.
** In "Mr. Monk Is On the Run" (both parts), Monk is framed for a shooting by a dirty county sheriff. Once Monk escapes, he finds the shooting tied to a plot to assassinate the governor.
** In "Mr. Monk Buys a House," the death of a wheelchair-handicapped man [[MakeItLookLikeAnAccident who fell down a flight of stairs in his own house]] is tied to money from an unsolved robbery.
** In "Mr. Monk and the Magician," Monk's upstair neighbor Kevin is killed by Karl Torini the night he debuts as an amateur magician = discrepancies in Torini's airline receipts that were evidence of Torini's involvement in a drug trafficking ring.
** In the TieInNovel ''Mr. Monk In Outer Space'', the heart-attack death of a fast-food company CEO that is dressed up as a shooting -> exposure of an embezzlement scam.
** In "Mr. Monk and the Paperboy", the investigation on who killed the paperboy who delivered Monk's paper led him to find out the plan of a girl to play BlackWidow to a multi-million-dollar lottery winner who lived in the same building (and who didn't even knew he ''had'' won, because the plan included keeping him ignorant of this fact).
** In "Mr. Monk Takes His Medicine", the investigation of a drive-by shooting in which Stottlemeyer gets shot in the shoulder turns out to be tied to an upcoming armored car robbery.
* Happens regularly in ''Series/PersonOfInterest''. Attempt to murder one person equals exposure of whatever crime they were trying to use the murder to cover up. This is actually The Machine's job, finding the simple links that would prevent terrorist attacks. The fact that it finds the same connections in more conventional crimes was purely accidental.
* ''Series/LoisAndClark'': Frogs being stolen from a pet shop → A conspiracy to replace the President of the United States with a clone who'd then sign a pardon for ComicBook/LexLuthor.
* ''Series/TeenWolf'': A dead woman is found in the woods → Werewolves exist, so do some other creatures, and there's a [[BuffySpeak war-type-thing]] going on between the werewolves, the other creatures, and the people who hunt them.
* ''Series/{{Elementary}}'': Murder of a conspiracy theorist → A member of a group that created a terrorist plot for a government training simulation that worked too well killing/mentally incapacitating the other members of said group to prevent knowledge of their plot from spreading. It turns out that the two cases are completely unrelated; the conspiracy theorist was killed by another conspiracy theorist over a disagreement about a different theory.
** Someone attempts to poison a prize race horse → the capture of a world-infamous drug cartel assassin.
** An older man is found dead of an apparent heart attack dressed in a leather gimp suit → the nanny of the dead man's children was accused of killing her abusive father in a similar way → turns out the dead man was a child molester who sexually abused his older son; the older son poisoned his father to prevent his little brother from being abused, and tried to frame the nanny.
** Detective Bell is investigating a break-in at a dockside warehouse → discovers his boss is a Mafia plant and barely averts a city-wide mob war.
* ''Series/AgentsOfSHIELD'': The pilot has the team investigating how an Average Joe gained superpowers. This leads to the discovery of [[NebulousEvilOrganization Project Centipede]]; the season-long investigation into this group and its [[TheGhost enigmatic]] leader, [[BigBad The Clairvoyant]], ultimately leads to the uncovering of [[spoiler: HYDRA's plot to destroy SHIELD from within]].
* From the ''Series/StarTrekTheNextGeneration'' two-part episode "Unification": Theft of a Vulcan ship from a scrapyard → Romulan plot to take over the planet Vulcan.
* A bomber in the third season of ''Series/TheWestWing'' is busted when he gets pulled over for a broken taillight.
* ''Series/{{JAG}}'': In "Brig Break", a handful of prisoners busting out of the brig gradually escalates into a plot [[spoiler: to destroy the base with a nuclear explosion and selling stolen nuclear weapons to UsefulNotes/SaddamHussein.]]
* ''[[Series/{{Daredevil 2015}}'': The exposure of a numbers racket inside Union Allied Construction LLC → the uncovering of [[ComicBook/TheKingpin a powerful figure controlling Hell's Kitchen]].
* Happens constantly in ''Series/MissFishersMurderMysteries''. For example, in "Death on the Vine" a simple case to investigate the origin of some mysterious photographs ends up exposing a TownWithADarkSecret.
* Subverted in ''{{Series/Dexter}}''. In season 1, while pursuing the Ice Truck Killer, the Miami PD comes across a man named Neil Perry due to his having traffic tickets issued near the scenes of the Killer's kidnappings. The subversion comes because the man is actually a computer hacker who specifically planted those minor pieces of evidence in order to lead the police to himself. Therefore he could falsely confess for the killings and be famous.
* The ''Series/{{NCIS}}'' episode "Enemies Foreign" starts with the team busting an identity thief. One of the identities she stole leads them to a pair of [[BadassIsraeli Mossad agents]] who are in D.C. in advance of Director Eli David--who is being followed by Palestinian terrorists who want him dead.
* ''Series/{{NewBlood}}'' is founded on one of these when the two investigators realise that their murder and fraud investigations are linked to each other and indicative of a larger conspiracy.
* The first episode of ''Series/TheNightOf'' follows, [[TwoLinesNoWaiting in parallel]], the detectives investigating a bloody murder scene and the street cops arresting a reckless driver who refuses to take a breathalyzer. We already know him as the guy who, earlier in the episode, woke up to a damning TheMurderAfter scenario and fled in a panic, but it's tense seeing the two investigations converge.

[[folder: Tabletop Games ]]
* One ''TabletopGame/{{Shadowrun}}'' supplement, about Lone Star Security, mentions how police in the Robbery division often wind up investigating major crimes: ones that'd started out ''looking'' like a simple robbery due to cover-up efforts by the perpetrators.
* This happens with amusing regularity to [[Literature/CiaphasCain COMMISSAR CIAPHAS CAIN, HERO OF THE IMPERIUM!!!]]. With the caveat that "minor crime" is usually a planet-engulfing war, and "major plot" is something with the potential to severely upset the balance of power across the ''galaxy''.
* ''TabletopGame/CallOfCthulhu'' supplement ''Masks of Nyarlathotep''. The murder of author Jackson Elias by cultists leads to a worldwide conspiracy to open a Gate and let the forces of the CthulhuMythos conquer the Earth.
* ''TabletopGame/MagicTheGathering'': In the ''[[Literature/RavnicaCycle Dissension]]'' novel, Agrus Kos is sent to infiltrate the Simic Combine to find out their involvement in a potential Dimir plot...and is surprised and chagrined when guildleader Momir Vig begins {{monologuing}} about his own, completely unrelated plan to TakeOverTheWorld.
* This is the standard structure for ''TabletopGame/{{Pathfinder}}'' Adventure Paths, to justify starting at level 1 (when [[Webcomic/TheOrderOfTheStick everything is kobolds and copper pieces, and you get excited over a potion of barkskin]]) and ending at 15-20 (when you can pick fights with legendary monsters and win): adventurers go to Town X at the behest of Patron Y, and whatever happens there starts them on a path to stopping the evil plan of Potentially Setting-Reshaping Threat Z. ''Iron Gods'' begins with someone sabotaging the purple "flame" that fuels most of the town of Torch's industry and ends with an unhinged AI launching a bid for godhood from within the confines of an ancient crashed spaceship. ''Carrion Crown'' starts with the apparently accidental death of a scholar, with the player characters being old friends attending his funeral, and winds its way through various horror tropes to an attempt to bring back an ancient lich. ''Legacy of Fire'' begins with a mysterious fire killing a merchant princess's personal astrologer, and the investigation ends with a crazed genie and his minions attempting to steal the power of an EldritchAbomination. There are others.

[[folder: Theatre]]
* The court case in ''The Broken Jug'' (Der zerbrochne Krug) by Heinrich von Kleist is about - you guess it - a broken jug. As it turns out, there is a particularily nasty case of blackmail behind it.

[[folder: Video Games ]]
* ''VideoGame/MaxPayne'': Murder of Alex Balder → Massive government conspiracy involving a failed attempt to create a SuperSerum for the military [[spoiler: which Max's family was killed to protect.]]
** ''3'': Kidnap attempt on Rodrigo Branco + kidnap of his wife Fabiana → cooperation between illegal paramilitaries and [[spoiler: {{Dirty Cop}}s]] → [[spoiler: organ harvesting of the poor, staged by a SleazyPolitician to get himself elected on an anti-crime ticket, with those cops being his private army.]]
* ''VideoGame/BaldursGate'': An Iron shortage due to bandit attacks → plot to spark a war between Baldur's Gate and Amn. Attempted assassination of some nobody orphan → resurrection/replacement of a dead god.
* Happens on occasion in the ''Franchise/AceAttorney'' series.
** The last case of the third game is probably the biggest example: the murder of a children's book author is ultimately tied into a gigantic revenge scheme.
** ''Investigations'': Seemingly disconnected murders of a police officer, a plane flight passenger, a prosecutor and a defendant → [[spoiler:An international smuggling ring. One that had a politician/ambassador of a country on the edge of war as the ringleader, incidentally.]].
** In the second case of the first game, trying to solve the murder of your mentor leads to you discovering [[spoiler:a massive blackmail chain]]. It gets better too: [[spoiler:the investigation reveals a reference to the "DL-6" incident, which becomes prominent later on.]]
** Almost every case in the fourth game has this.
*** Murder of a unknown guy in a restaurant - [[spoiler:Victim is actually protagonists step-father, defendant's old client and the real murderer's motive is tied to do with the events of seven years ago]].
*** None-fatal hit and run, a panty-snatching and the theft of a noodle stand leads to a murder where [[spoiler:the defendant is the son of the city's biggest crime boss, and is also all but dead thanks to a turf war that caused him to get shot]].
*** The murder of a singer's manager during a concert is pretty big, but [[spoiler:when that manager turns out to be an Undercover Interpol Agent who was killed by a smuggler of a substance that is on the top of Interpol's list, it gets even bigger]].
*** An isolated painter is found dead. [[spoiler:Oh, and he happens to have drawings depicting all the cases that the titular character has worked on up to that point]]. And as if that wasn't enough [[spoiler:he turns out to be a forger who was apparently responsible for making the evidence that got Phoenix disbarred seven years ago. And to top it all off, it turns out that his murder was actually ''supposed to happen'' seven years ago during those events, but the "time bomb" that the killer set for him got delayed, thanks to some luck, that happens to tie into the Apollo's Sister's family being a group of famous magicians]]. ...Quite a complex web for a case that starts out as your run of the mill murder.
** ''[[VisualNovel/PhoenixWrightAceAttorneyDualDestinies Dual Destinies]]'' also counts. Bombing of Courtroom No. 4 → [[spoiler:an international spy destroying evidence that would reveal his identity ''and'' his guilt in a seven-year-old murder, ''and'' the murder and impersonation of a police detective, ''and'' two consecutive terrorist attacks on the Space Center. ]].
* In ''VideoGame/PoliceQuest 3'', the endgame involves the investigation of a house linked to a series of murders. When it turns out that the place is fortified, the player must go back to the courthouse and get authorization to use the departmental battering ram, which uncovers a cocaine manufacturing ring.
* ''Franchise/MassEffect'': An unprovoked attack on a human colony → [[spoiler:The destruction of all sentient life by {{Eldritch Abomination}}s.]]
** The sequel gives us: Human colonies disappearing → [[spoiler:Creation of an EldritchAbomination.]]
** The ''Arrival'' DLC has: Admiral Hackett's friend Dr. Kenson has been kidnapped by Batarians → [[spoiler:Eldritch Abominations will arrive and begin the galactic extermination in 2 days.]]
* The entirety of ''Franchise/ResidentEvil'' and its mess of a biological war can be traced back to [[VideoGame/ResidentEvil the first game]] and [[VideoGame/ResidentEvil0 its prequel]] - an investigation of the murder of ten people, [[ImAHumanitarian seemingly eaten]], allows the massive conspiracy behind Umbrella and its viruses come to light.
* This happens in every game in the ''VideoGame/JakAndDaxter'' series:
** In ''VideoGame/JakAndDaxterThePrecursorLegacy'', the quest to change [[WeaselMascot Daxter]] back to normal resulted in the group stumbling on a plan to flood the world with [[PsychoSerum Dark Eco]].
** ''VideoGame/JakIIRenegade'', in which Jak is out for revenge against [[AristocratsAreEvil Baron Praxis]], leads to him saving the city from the [[EldritchAbomination Metal Head Leader]].
** ''VideoGame/Jak3Wastelander'' opens with Jak and Daxter only trying to survive in a harsh new environment, and ends up pitting them against an OmnicidalManiac working for [[TheCorruption dark versions]] of the {{Precursors}}.
** In ''VideoGame/JakXCombatRacing'', Jak and friends are coerced into entering a competition, only to find out they're in the middle of a gang war.
** In ''VideoGame/{{Daxter}}'', Daxter's just trying to make a living and figure out how to rescue Jak, only to to uncover the brewing invasion plot by the Metal Heads.
** In ''VideoGame/JakAndDaxterTheLostFrontier'', Jak, Daxter and [[ADayInTheLimelight Keira]] set out to find more eco and restore balance to the world, but things [[ItsShortSoItSucks quickly]] escalate into stopping a power-hungry madman.
* ''VideoGame/ChronoTrigger'': SaveThePrincess → Prevent the EndOfTheWorldAsWeKnowIt.
* ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]'': Exorcise a walking spirit and deliver a letter → Shape the future of TheEmpire.
* ''VideoGame/DragonAgeII'': Sneak a free Qunari mage out of Kirkwall → [[spoiler:Halt a Chantry plot to spark open conflict between humans and Qunari]].
** Humorously played with the Bone Pit mine, going from an invasion of small dragons to a Coterie plot to steal shipments to a [[OurDragonsAreDifferent High Dragon]] taking over. One of the miners called it, too.
* ''VideoGame/{{Touhou}} 8: Imperishable Night'': BadMoonRising → alien conspiracy from the antiquity.
** ''Touhou 11: Subterranean Animism'': Strange creatures from BeneathTheEarth → nuclear conspiracy going out of hand.
** {{Inverted|Trope}} in ''Touhou 12: Undefined Flying Object'': cultists trying to awaken Pandemonium monstrosity → decent people wanting their saintly leader back.
** {{Inverted|Trope}} again in ''Touhou 13.5: Hopeless Masquerade'': people mysteriously loosing hope → innocent newborn youkai trying to regain control of her emotions.
** ''Touhou 14.5: Urban Legend in Limbo'' and ''Touhou 15: Legacy of Lunatic Kingdom'': UrbanLegends suddenly start to become real → [[spoiler:Invasion by the {{Lunarians}}, forced about as a result of a resentful divine spirit laying siege to their homeland.]]
* ''VideoGame/{{Persona 3}}'' has your team investigating the mystery of the Dark Hour and why your school turns into a freaky tower every night. You end up [[TheEndOfTheWorldAsWeKnowIt saving the world]]
** ''VideoGame/{{Persona 4}}'' has you and your team exploring The Midnight Channel and stopping people from being killed by facing their [[EnemyWithout enemies without]]. You end up uncovering [[spoiler: a DirtyCop and an AssimilationPlot by the goddess Izanami to turn everybody into Shadows and form one, collective conscience.]]
* The standard plot of ''VideoGame/TexMurphy'' games. Tex gets a small, simple gig (find my missing friend) and it turns into a save the world scenario.
* ''VideoGame/FalloutNewVegas'': Find the man that shot you and stole the package you were supposed to deliver, get said package back, and finish the delivery → decide which of the factions vying for control of New Vegas and the rest of the Mojave Wasteland emerges triumphant, or [[ICanRuleAlone make your own power play and take over for yourself]].
** There are others, too.
*** Prostitutes being abused → [[spoiler:Omertas plotting to attack the Strip]].
*** Sabotage of an NCR base → a terrorist attack on the monorail.
*** False radio reports → high treason
* True to its genre, ''VideoGame/LANoire'' has one: Series of house fires → [[spoiler:a giant real estate scheme]].
* ''VideoGame/NeverwinterNights2: Storm of Zehir'': Sabotage of a trade ship → [[spoiler:yuan-ti plot to take over the world]].
* ''VideoGame/EternalDarkness'': Investigate your grandfather's violent murder → Stop a two thousand year old [[OurLichesAreDifferent "liche"]] from summoning a world-destroying EldritchAbomination.

* ''[[VideoGame/FireEmblemElibe Fire Emblem]]'': A minor noble from Lycia goes missing, and another minor noble plots rebellion → A mad sorcerer was using those nobles to try to summon dragons to destroy the world.
* Happens quite a bit with the villain teams in ''VideoGame/{{Pokemon}}''. For example:
** ''VideoGame/PokemonRedAndBlue'': Fossil theft in Mt. Moon → A plot by Team Rocket to TakeOverTheWorld and enslave all Pokémon.
** ''VideoGame/PokemonGoldAndSilver'': Slowpoke losing their tails in Azalea Town → An attempt to restore Team Rocket to its former glory by a few senior operatives trying to get the former Boss Rocket's attention.
** ''VideoGame/PokemonRubyAndSapphire'': An attempt to steal a Devon researcher's papers → An ecoterrorist plot to either expand humanity's grip on the Earth or return what humans stole to Pokémon, involving a very powerful Legendary.

* ''Webcomic/TheOrderOfTheStick'': [=Murder/robbery=] of Eugene Greenhilt's mentor → [[spoiler:Multiverse-spanning plot to gain control of an EldritchAbomination that could destroy the world and kill the gods]]

[[folder: Web Original]]
* ''Literature/TheSalvationWar: Pantheocide'': Discovery of illegal human items in Heaven → [[spoiler: multiple conspiracies to bring down Yahweh]].
* ''WebVideo/TheCartoonMan'' trilogy: Missing persons case. → [[spoiler:A plot by said missing person to enslave the world]]
* ThisVeryWiki:
** IEatMetaphorForBreakfast and WhatYearIsThis being sent to TRS → massive epidemic of TropeDecay involving stock phrases as trope names.
** Spoiler policy abuse being directed towards the protection of a villain's identity on Characters.{{Frozen}} → rampant abuse on Character pages in general.
** Some people insisting that [[RuleOfCautiousEditingJudgment The Scandal That Shall Not Be Named]] is an example of {{Scandalgate}} → TropeDecay running rampant on that very page.
* The creepypasta ''Teacher Wanted, Must Love Kids'' has one hell of an example: Male teacher is fired for allegedly groping female student. → [[spoiler: Female teacher framed him to cover up the fact that she's an EldritchAbomination doing ''[[MindRape much worse]]'' things with the male students]].

[[folder: Western Animation ]]
* ''WesternAnimation/AmericanDad'': Parodied, and played straight. Steve does a research project on peanut butter and discovers a secret conspiracy dating back to the days of Abraham Lincoln. The parody occurs earlier in the episode in the form of a NoodleIncident where Snot claims that he gave up sleuthing after "the case of a missing bike horn turned into a double rape homicide".
* 1973-74 ''WesternAnimation/SuperFriends'' episode "The Planet Splitter". The theft of diamonds weighing 100+ carats → A plot to split Cygnus Uno, a planet in another solar system.

** "Mona Leaves-a": Homer fulfills his late mother's final wishes → Uncovering Mr. Burns' plan to send a rocket full of radioactive waste to the Amazon rainforest.
* WesternAnimation/Ben10AlienForce's 1st two-part episode has alien weapon smugglers on Earth. Magister Labrid was correct saying "That's just the tip of the iceberg", as it's discovered later on that said smugglers were gathering enough cash in the black market to fund their Galactic scale ApocalypseHow plan.
* A common plot in ''WesternAnimation/ChipNDaleRescueRangers''. Finding a missing kitten --> foiling a plot by a mad scientist to level the city with lightning. Reuniting a nightingale with a Chinese ruler → foiling a plot by said ruler's sister to take over the throne. Helping a kid find his lost science project → foiling a plot by the same mad scientist wanting to level the city...again. An attack on a fish truck → stopping a submarine full of seas creatures from flooding the city. Even their first mission had a case of a stolen ruby turn out to be part of a scheme to rob the world gold depository.
** One such episode even has Chip lampshading the idea: he doesn't want to help a bird migrate to Capistrano because the case is "too small", only for it to turn into a case of a woman using a giant magnet to screw up birds' sense of direction in order to capture them and bake them into pies, which ends up bringing down an entire airplane in the end.
* ''{{WesternAnimation/Gargoyles}}'' begins with Elisa investigating the relatively minor crimes of property damage and theft, and this investigation exposes her to the major plot from the very beginning.
* ''WesternAnimation/YoungJustice'': The first outing (unofficial, at that) of the Team is to investigate a fire at Cadmus Labs. The fire allows them to uncover a vast secret project to create genetically engineered soldiers... including Superboy. [[spoiler: It's also the first glimpse into the operations of the Light, who are secretly responsible for every villainous act in the series]].
* ''WesternAnimation/KimPossible'' has this happen quite a few times. The biggest example is from ''WesternAnimation/KimPossibleMovieSoTheDrama'' where the attempted kidnapping of a toy magnate was merely the first step in Drakken's most ambitious TakeOverTheWorld plot.

[[folder: Real Life ]]
* ''The Cuckoo's Egg'' tells of how astrophysicist Clifford Stoll was asked to resolve a [[UsefulNotes/AmericanMoney 75¢]] discrepancy in the Lawrence Berkeley National Laboratory computer usage accounts, and ended up uncovering a German computer hacker selling secrets to the KGB.
* [[{{Scandalgate}} Watergate.]] A foiled "third-rate" burglary at the Watergate complex → the subsequent investigation by ''Washington Post'' reporters Bob Woodward and Carl Bernstein uncovered diverted funds and a conspiracy to manipulate the US election that went right up to the [[UsefulNotes/RichardNixon President himself]]. As well as adding [[{{Scandalgate}} a new suffix to the English language]].
* The Los Angeles Police Department '''Rampart Scandal''' in the late 1990s, which was the inspiration for the movie ''Film/TrainingDay'' and the TV series ''Series/TheShield'':
** It started when Rampart CRASH officer Kevin Gaines was shot dead in self-defense on March 18, 1997 by undercover LAPD officer Frank Lyga in a road rage incident in March 1997. The resulting investigation revealed prior road rage incidents involving said CRASH officer, and the reveal that he was living a lifestyle far beyond what his annual LAPD salary would afford, and had been associated with Death Row Records CEO Suge Knight; and that Death Row Records, which had gang ties with the Bloods, hired off-duty LAPD police officers to serve as security guards.
** The investigation into Gaines also led to detectives suspecting that he and other corrupt cops were involved in the murder of the rapper Notorious B.I.G. in a drive-by shooting.
** Ultimately, in March of 1998, eight pounds of cocaine worth $800,000 were stolen from an evidence room. Rampart CRASH Officer Rafael Pérez was arrested for the theft and it was suspected to be an attempt to frame Frank Lyga in retaliation for Gaines's death, as the cocaine stolen had been booked into evidence in a prior arrest that Lyga had made. Perez also was suspected of having knowledge about the illegal activities of another CRASH officer, David Mack, who had robbed a bank that his assistant manager girlfriend worked at in November 1997. When Perez got a mistrial, he took a plea bargain and pled guilty to cocaine theft in exchange for providing prosecutors information about two "bad" shootings and three other Rampart CRASH officers engaged in illegal activity. Ultimately, over 4,000 pages of sworn testimony came out of Perez, which resulted in more than 70 officers being implicated in serious misconduct. This went even further as the scandal led to the Police Chief, District Attorney, and Mayor of Los Angeles all eventually being not re-appointed or re-elected (after allegations arose that the chief had tried to censor the lead investigators in the Rampart case, and one of these detectives resigned as a form of protest). Over 100 criminal convictions were also overturned as a result.
* Accountants are taught to consider even tiny discrepancies in financial data important, as even the smallest shortfall can be a clue to large-scale embezzlement or fraud.
** Enron is an example of this. Initially, the only question people had about Enron was whether its stock was overpriced. People trying to figure that out found themselves trying to untangle the incomprehensible accounting practices Enron used, which led to more questions and eventually, the whole scandal (and company) imploded in fraud charges.
* Some of the most infamous murderers in history have been caught thanks to them tripping up over traffic violations:
** They certainly already knew about the crime, but Timothy [=McVeigh=] was initially arrested 90 minutes after blowing up the Alfred P. Murrah Federal Building in Oklahoma City for driving without license plates and (as the officer noticed on pulling him over) having an illegal gun. [=McVeigh=] nearly made bail before he was connected with the bombing.
** David Berkowitz, the 'Son of Sam' serial killer, was tracked down because his getaway car was ticketed for illegal parking at the scene of one of his murders.
** Ted Bundy's initial capture was this: On August 16, 1975, an off-duty cop driving around his own neighborhood in a suburb of Salt Lake City saw a Volkswagen Bug that didn't belong there driving with its lights off. Bundy promptly took off. The cop eventually chased him down and cited Bundy for failure to stop for an officer and possession of burglary tools. A detective connected Bundy with an open case of kidnapping and attempted murder. He was soon linked with some two dozen murders and became America's most notorious serial killer. This happened ''[[RealityIsUnrealistic two more times]]''. After he was convicted of kidnapping in Utah, Colorado extradited him to face a murder charge. Bundy managed to escape (''after'' an attempted escape in Utah), but was pulled over in a stolen car weaving in and out of the lanes. He then managed to escape ''yet again'' from a Colorado jail and went to Florida, where he killed two more women. He was then stopped in ''[[WhatAnIdiot another]]'' stolen car by a patrol officer making a routine check, and captured for the last time.
** Serial killer Joel Rifkin initially drew the attention of a patrolman for driving without a license plate. When he was stopped (after a high-speed chase), police found the body of a dead prostitute in the trunk. Rifkin was eventually convicted of 17 murders.
** Similarly, Leonard Lake and Charles Ng kidnapped and killed upwards of 25 people together and were only stopped when Ng was caught shoplifting from a hardware store, having driven there in a car that belonged to one of their victims. Lake was taken into custody where he promptly [[CyanidePill killed himself]] knowing it was all over, but Ng managed to evade authorities until he was again busted while [[WhatAnIdiot shoplifting]].
* The Charles UsefulNotes/MansonFamily was originally arrested for car theft, and it wasn't until one of them bragged to a fellow inmate that they were implicated in the string of high-profile murders occurring at the time.
* The "Festina Affair" that first blew the lid off the systematic doping by teams at the Tour de France in 1998 began with one of the Festina team's cars being routinely stopped by customs at the France-Belgium border and the discovery of steroids, EPO, syringes and other paraphernalia in the car's trunk.
* In ''Film/NineEleven'', a documentary about 9/11, this trope happens. Jules and Gedeon Naudet and James Hanlon are making a documentary about probationary firefighter, Tony Banatatos, in his journey to become a full fledged firefighter in New York City. Weeks go by and they get great footage of the life of firefighters, but no "real" fires happen. Then, the firefighters investigate a gas smell. The date? September 11, 2001. While filming this, Jules captured American Airlines Flight 11 hitting the north tower of the World Trade Center—the only footage of the first plane's impact.
* Real life police officers are taught to take extreme care when pulling over a car at a traffic stop because of this trope. If the driver is being pulled over for a traffic violation like speeding or reckless driving, but he committed a much more serious crime, he will likely believe he's being pulled over for the latter and might try to take off. Or start shooting.
* It's possible for someone abducted and locked in the trunk of a car to invoke this trope. If the car is an older model or the interior trunk release is disabled, it may be possible to pry off the lining to get at the cords leading to one of the tail lights. Disabling one increases the chance that the car will be noticed by the police for the minor violation.
* [[https://en.wikipedia.org/wiki/The_PTL_Club#Scandal_and_subsequent_demise The PTL scandal]] could have its beginning linked to a 1980 scandal involving a sexual encounter between PTL founder Jim Bakker ([[spoiler:temporarily separated from then-wife Tammy Faye]]) and a young church secretary named Jessica Hahn (depending on whether you believe either Hahn's account; accusing Bakker of essentially date raping her, or Bakker's version, stating the sex was consensual and possibly an attempt at revenge due to Tammy Faye's infatuation with music producer Gary S. Paxton). What got the Charlotte Observer's attention was initial concerns of financial misdeeds such as the $1,000 lifetime partnerships for their [[TheMoralSubstitute Heritage USA]] theme park, along with later revelations that $265,000 was given to Hahn as "hush money" to keep the incident quiet.
* In the 2003 Antwerp diamond heist, which is one of the largest at over $100 million, the criminals were largely caught thanks to littering when they made a rather unlucky choice of where to dump their trash and it was quickly found the next day by an annoyed resident.
* Deliberately invoked by the IRS in order to nail AlCapone. They determined that it was going to be impossible to indict him for his mob's innumerable violations of the Prohibition laws, or their almost as numerous cases of bootlegging, blackmail, extortion, murder, and racketeering, because Capone had all of the local police in his pocket and no witness brave enough to testify without the fear of getting whacked as retribution, and if he was brought to trial, he bribed or intimidated the juries into delivering "not guilty verdicts". So they hit him for what they ''could'' prove: income tax evasion, as he failed to pay taxes on this undeclared revenue of his.
** Other notable crime lords, like Mickey Cohen, were also brought down in the same way. Even though he engaged in a number of illegal activities, it was tax evasion that he was nabbed for.
* In 2012, a chef at the Virginia Governor's Mansion was fired for stealing food from the mansion. The investigation into this small time petty crime ended up revealing a far more serious crime involving Governor Bob [=McDonnell=] accepting extremely expensive gifts in return for illegally using his office to market a dietary supplement. The chef ended up with two misdemeanor embezzlement charges, while [=McDonnell=] and his wife were convicted of a combined ''19 felony charges'' relating to corruption and fraud.
* In April 2011, sheriff's deputies in Gloucester County, Virginia, searched a home for stolen property. [[http://hamptonroads.com/2011/06/gloucester-residents-dark-child-abuse-came-light They found]] a six-year old girl near death, locked in a cage, apparently having been hidden from society for most of her life. [[FromBadToWorse And her brother's remains buried under a shed.]]
* After assassinating UsefulNotes/JohnFKennedy and Officer J.D. Tippet, Lee Harvey Oswald was nabbed while sneaking into a movie theater without paying a ticket. The theater manager suspected Oswald might be more than a petty criminal and called the cops.
** Although Jim Garrison's [[https://en.wikipedia.org/wiki/Trial_of_Clay_Shaw prosecution]] of Clay Shaw has been generally ridiculed by serious assassination researchers, Oliver Stone found the way it spun out of a fight between two low-rent private eyes to be fascinating, which led to the movie ''Film/{{JFK}}''. He said "This pistol whipping occurs on the night of November 22, 1963, on a rainy night in which this guy, Jack Martin, gets his skull laid open by his boss, Guy Banister, and out of that little Creator/RaymondChandler kind of incident, Garrison spins this tale of international intrigue -- a hell of a trail. As a dramatist, that excited me."
* Malcolm Webster, the Black Widower, was tripped up in this manner. Alleged embezzlement of angler club funds → murder of Claire Morris, his first wife, and attempted murder of Felicity Drumm, his second wife.
* Britain's most prolific serial killer, Dr. Harold Shipman, was originally investigated over allegations that he had forged the will of a recently deceased patient. The fake will was traceable to his typewriter, which led to the patient being exhumed. Traces of diomorphene were found in her body, and other apparently healthy patients who died suddenly were then also exhumed. It has been suggested that Shipman deliberately invoked the trope himself, making the ham-fisted forgery because he ''wanted'' to be caught.
* A pair of ''Los Angeles Times'' journalists investigating small-time malfeasance in Maywood, California, then stumbled across [[https://en.wikipedia.org/wiki/City_of_Bell_scandal a much larger, far-reaching embezzling scheme in the neighboring town of Bell]]. Despite having a population of 35,000, three of its leaders had annual incomes higher than the President of the United States. The embezzlement is so complicated and intense that it threatened to suck the people of both Bell and Maywood dry of money, and five years later, the FBI is still discovering new ways that Bell officials had siphoned money into their hands.
* The 1962 assassination attempt on French President UsefulNotes/CharlesDeGaulle was solved when a wanted Foreign Legion deserter was detained for not having papers at a police checkpoint.
* On April 20, 2007, Davon Boddie was arrested for pot dealing outside of the Royal Suite nightclub in Roanoke, Virginia. Boddie was the cousin of [[UsefulNotes/AmericanFootball Atlanta Falcons quarterback]] Michael Vick, and gave Vick's home address as his own. Five days later, police searched the home and discovered a massive [[http://en.wikipedia.org/wiki/Bad_Newz_Kennels_dog_fighting_investigation dog-fighting ring]], leading to the arrest and conviction of Vick and four others.
* In 2005, a former Brazil Postal Service executive was filmed negotiating a bribe, while saying he had the backing of a congressman. Said politician went on to reveal [[https://en.wikipedia.org/wiki/Mensal%C3%A3o_scandal the government was buying the support of a lot of deputies]]. If that wasn't big enough, a decade later a money laundering operation using a gas station uncovered [[https://en.wikipedia.org/wiki/Operation_Car_Wash a massive corruption scheme]] that sunk the value of the country's biggest company and made the president go through an impeachment process.
* What started as an investigation into the attack on Benghazi in 2012 would over the course of just a few years mushroom into one of the biggest Presidential controversies this side of Watergate as Hillary Clinton's handling of classified emails came into question as she was preparing to run for the Democratic ticket of the 2016 Presidential election.
* In late 1670s France, an investigation into a forged marriage certificate led to the exposure of a massive network of poisoners, one that reached as far as the inner circle of UsefulNotes/LouisXIV. The "Affair of the Poisons" became one of the greatest scandals in French history.
