One of the heroes has been captured by the bad guys. His friends know where he's being kept, but the dungeon lies deep within the villain's impenetrable fortress, surrounded by guards, and a good old-fashioned prison break simply won't do.

However, it just so happens that one of the opposition has been spotted wandering around outside Camp Good Guy, and was conveniently dumb enough to get caught. Now there are two captives, one in each camp.

So what do the two opposing sides do in this situation? Each has something the other wants, and neither is willing to let up unless they can find a way to use the situation to their advantage. So they agree to trade hostages. They meet up at a certain location where the exchange will take place, both prisoners get to go free, and everyone's happy. Right?

Usually the captured member of the other team is no ordinary {{Mook}}. He may be someone who is important to the villain in some way, someone he [[MoralityPet cares about]] or [[MacGuffinGirl needs]] in order to fulfill his EvilPlan, otherwise the other side would not bother with trying to get him back. Heroes usually don't need this kind of motivation to rescue a captive comrade, as they generally need less of a reason to save people. A MessianicArchetype may risk both his life and the chance of giving up whatever advantage he may have had, coupled with letting a villain go free, in order to save a total stranger, although it's just as likely that the captive will be someone close to the hero in order to facilitate drama.

The exchange often involve both sides facing each other across a wide open area. Each captive walks toward the other, they pass by each other in the center and proceed on to their own group. [[TakeItToTheBridge Often takes place on a bridge]], since it marks the only crossing point of a natural barrier, such as a river or chasm, [[BorderCrossing where two territories would typically be divided]]. It also gives both sides a clear view of each other as well as of the hostages in case anyone tries anything funny (providing there is no OminousFog), and can be symbolic for the hostages making their journey home.

Note that the downside of this agreement is, because EvilIsPetty, villains rarely make fair trades. While a hero will be bound to keep his word and make sure that the hostage is returned to the villain unharmed, the villain will often take the first opportunity to kill his hostage as soon as he gets what he wants, or to cause the heroes to walk into a trap, or [[YouSaidYouWouldLetThemGo find some other way to go back on his promise]].

GenreSavvy good guys or [[AntiHero Anti Heroes]] may realize this and never intend to make a trade with the villain in the first place, or both sides may have the intention of screwing each other over, in which case the hostages themselves rarely have any say in the matter and may end up on the worse end of the deal.

If the hero decides to trade him/herself for the hostage, it's TakeMeInstead. See also HostageSituation and CheckpointCharlie.

[[folder:Anime and Manga]]
* In ''Lightnovel/FullMetalPanic'', Sousuke has to make the decision of trading his hostage for either [[LoveInterest Kaname]] or Tessa. He picks Tessa, knowing that Kaname can protect herself just fine, and her ActionGirl instincts means that she'll [[SpannerInTheWorks mess up]] the bad guys plans by reacting in a way they [[DidntSeeThatComing don't expect]].
* In ''Anime/ReadOrDie'', Yomiko trades Joker for Nenene... only to learn that Wendy hadn't captured Nenene at all. She had just asked the British Library's resident MasterOfDisguise to impersonate Nenene for the exchange so that they could get Joker back.

[[folder:Film]]
* Film/JamesBond is exchanged for Zhao in ''Film/DieAnotherDay''.
* Sergio Leone's ''A Fistful Of Dollars''.
* In the JohnWoo movie ''A Better Tomorrow'', an exchange between BigBad Ah Shing (who the first protagonist, Sung Tse Ho, has captured) and Ho's little brother Sung Tse Kit (the other protagonist, who Shing's {{mooks}} have at gunpoint) sets off the final battle of the movie.
* In the Creator/JohnWayne film ''Film/RioBravo'', the heroes captured the brother of a bandit leader before the start of the movie, and the plot is driven by the bandit's schemes to rescue his brother before the US Marshall arrives. One such plot involves kidnapping a sheriff's deputy and trading him for the brother. Unusually for this trope, we never get any indication of whether or not the villains intend to play fair, as it's the heroes that play dirty and go in with every intention of leaving with both prisoners.

[[folder:Literature]]
* In ''[[{{Redwall}} Mattimeo]]'', the Redwallers capture General Ironbeak's three magpies, who are his only way of getting supplies, and trade them for the three Redwall hostages. Unfortunately, Ironbeak is smart enough to use the PrisonerExchange as a cover while he sends his troops to steal as much food as they can from Redwall.
* In ''Literature/LesMiserables'', Enjolras and Combeferre were about to suggest exchanging Javert for Jehan Prouvaire (who had been captured by the National Guard), but experienced something of a timing failure.
* in a more hostage for macguffin girl way, Farworld sees the dark circle kidnap Dew in order to trade her for Kyja, who is a 'guest' of the water elementals.
* There's a form of this in the XWingSeries book ''Wedge's Gamble''. There is an Imperial prison which Rogue Squadron can access, and a corrupt warden who will make deals. The prison has Rebels and scum of the galaxy, the latter group being the one that gives the warden more trouble. Said warden will let the Rogues retrieve some Rebels, but only if they also take some of that scum, too; namely members of Black Sun, a criminal empire which has dissolved. Little does he know that the Rogues are there for the scum so said scum can be recruited in a labyrinthine plot - the Rebels are just a nice bonus.
* The third ''Literature/SkulduggeryPleasant'' book has a scene on Dublin's Liffey Bridge, where the heroes have to trade Fletcher, the only person in the world who can open the gate for the Faceless Ones, to the Diablerie in exchange for Grand Mage Thurid Guild. Naturally, they all double-cross each other multiple times. [[spoiler:The Diablerie has exactly one more double-cross than the heroes.]]
* When the Havenites and Manticorans discuss prisoner-of-war exchanges in the later ''Literature/HonorHarrington'' books, at least one character muses on what a fair exchange rate on prisoners would be, given that most battles had been stacked heavily in favor of the Manticorans' superior training and technology versus the Havenites' massive quantity of ships and troops.
* In ''ASongOfIceAndFire'' Catelyn suggests trading Jaime Lannister for her daughters, whom she supposes are being held hostage by the Lannisters. It doesn't go through.
* ''[[Literature/TheQuestForKarla]]'' sees the Circus agreeing to exchange [[spoiler: mole Bill Haydon]] for their remaining agents in the Soviet bloc that haven't been shot. However, it falls through when [[spoiler: Haydon is killed, presumably by Jim Prideaux]].

* Once on ''Series/GetSmart'' KAOS kidnapped the Chief, so Control captured one of KAOS's agents to try to make a deal. KAOS captured another - back and forth until the only non-prisoners were Max and Sigfried, who arranged an exchange. KAOS got the last laugh when, during the exchange which was two big busses full of prisoners, KAOS captured the Control bus driver.
* One of these takes place in ''Series/{{Heroes}}'' Volume 2. Bob, the head of [[TheMenInBlack The Company]], kidnaps Claire. Claire's father, [=HRG=], kidnaps Bob's daughter [[PsychoElectro Elle]], and attempts to trade her to get ''his'' daughter back.
* On ''Series/{{Lost}}'', Jack suggests offering the captive "Henry" in exchange for Walt, who has been kidnapped by the Others. Unfortunately, the Others had a different plan.
* Happens in ''Series/RaumschiffGamestar'', with Darth Mopp being exchanged for Communications Officer Mikkl. Naturally, while both sides are negotiating the conditions, the prisoners escape on their own...
* Happens without incident in the mini-series ''Series/{{V}}: The Final Battle'', when the BigBad Diana exchanges Donovan's son for one of her own men. Of course, Diana has no reason to stop the exchange because she's "[[{{Brainwashed}} converted]]" Donovan's son into becoming her spy.
* Sark is swapped in this way early in the third season of ''Series/{{Alias}}''. A third party messes it up, a gunfight breaks out, and the bad guys make off with both hostages.
* In ''Series/TheXFiles'' Mulder performs such a trade between Scully and [[spoiler: an alien clone he believes is]] his sister Samantha. In this case, though, it's the good guys who aren't playing fair and have a sniper standing by to shoot the kidnapper once both hostages are clear.
* In the ''Series/DoctorWho'' episode "Time and the Rani" the Doctor trades the Rani for his companion Mel in this way.
* Subverted in an early episode of TheSandbaggers. The hero's girlfriend has been captured in East Germany and everyone agrees to a trade. [[spoiler: He has a sniper [[ShootTheHostage shoot her down]] when she's halfway across so that the trade cannot take place.]]
* An episode of ''Series/MagnumPI'' involved an exchange which traded an American POW from Vietnam for the man who killed Magnum's wife.
* Season 2 of the 2010 ''Series/{{Nikita}}'' saw a hostage exchange between Team Nikita and Division. Thanks to [[MagnificentBastard Percy]] being half the exchange, [[GenreSavvy Nikita]], and the show's GambitPileup (there's ''four'' factions playing) tendencies, the whole thing goes to hell. Only Team Nikita comes out ahead.

[[folder: Mythology]]
* In ''InannasDescentToTheNetherworld'', Inanna (later known as Ishtar) went to [[TheUnderworld Irkalla]] to try and take over, but was defeated by her sister Ereshkigal. Meanwhile, above ground, nobody is having sex, plants are dying, etc. So Inanna arranges to be brought back to life, and Ereshkigal agrees to let her go...on one condition: [[BalancingDeathsBooks that she find someone to take her place.]] Inanna searches for someone, but finds no one that she ''really'' wants to send to Irkalla. Then she sees her husband Dumuzi (Tammuz) lounging around under a tree instead of openly mourning for her. [[note]] In some versions, he is [[YourCheatingHeart having sex with some other woman.]][[/note]] This enrages Inanna because it makes her think he doesn't care about her, so in a fit of hurt and anger, she chooses him to go in her place. His sister begs her not to do that, saying TakeMeInstead...and eventually Inanna [[MyGodWhatHaveIDone regrets sending her husband down there]]. So an agreement is made: Dumuzi lives in Irkalla for six months, and his sister switches with him for the next six. [[JustSoStory While he's down there, nothing grows, but while he's with Inanna, everything is allowed to grow again]].

* Sometimes happened during the ColdWar between the U.S. and U.S.S.R. with captured spies, most famously across the Glienicke Bridge.
** In 1962, KGB agent Rudolf Abel was swapped for American pilot Gary Powers Jr. (who had been captured after his U-2 spy plane was shot down over the USSR.
* The 2010 swap of ten [[DeepCoverAgent Russian agents]] captured in the US for four people held in Russia.
* Done ''en masse'' during the days of WoodenShipsAndIronMen where there were regular truce ships going back and forth carrying prisoners. The two sides kept regular tabs on each other's debit and credit. Sometimes this would break down mid-war, for instance when one side decided that the enemy was running out of manpower and needed to be squeezed harder. Like other such customs, aspects of this hung on as late as WorldWarII, though it was mostly disabled prisoners who were exchanged.

[[folder:Video Games]]
* In VideoGame/CovertAction, this option is available to players that get captured. You can opt to wait a several hours to escape instead.
* RedDeadRedemption uses this. Norman Deek is being traded for the ShipTease, and surprisingly enough, they don't want the prisoner back.
* Trading a hostage for one of your partners in crime is strongly encouraged in VideoGame/PAYDAYTheHeist.
* In ''VideoGame/CallOfJuarezTheCartel'', the protagonists intend to exchange Juarez's son for Jessica Stone. [[spoiler:Alvarez shoots both at the exchange]].
* During ''VideoGame/DmCDevilMayCry'', Kat is taken prisoner by Mundus, and Dante eventually gets his hands on Lilith and her child, the latter of which is Mundus' heir. Dante arranges for an exchange between them to save Kat, and both Dante and Mundus' officers conduct the exchange in a professional manner. [[spoiler:Vergil, however, had no such compunctions, and shoots Lilith and the baby dead midway through the exchange, turning the relationship sour in record time.]]
* A prisoner swap opens the Battle of Mt. Ding Jun in ''VideoGame/DynastyWarriors 4''. Wei's Xiahou Shang is traded for Shu's Chen Shi. The two slowly walk towards each other across an open field while observed by generals from both sides, but the moment one passes the other, both break out into a run for their own lines. That appears to be the cue that the prisoner exchange is over, as arrows start flying from both sides immediately afterwards. This curtly concludes the cease fire and leads directly to the battle itself.
