"You may find yourself living in a shotgun shackThe characters are locked in, have no idea how they got there, why they're there, or how to get out, nor do they know exactly who is behind their predicament, if anyone. The main thrust of such stories is the investigation of the restricted environment in which the characters find themselves, with the goal of mastering it, revealing its secrets, and eventually escaping. Often those approaching the truth are sharply yanked back. The genre is usually a metaphor for the unknowns and Big Questions of Real Life: what is my purpose, why are we here, what can be done to solve the unsolvable? May overlap with Small Secluded World, World Limited to the Plot, Alternate Universe, Planet of Hats, Adventure Towns or Lotus-Eater Machine. Almost always employs Failure Is the Only Option and a veritable swarm of Schrodinger's Butterflies to obfuscate issues. There's usually a Straw Nihilist in the cast saying it's all pointless. See also the Quest for Identity, where the main character doesn't even know who he is. A subtrope of the Driving Question. The simpler versions are You Wake Up in a Room. Often spawns an Escape from the Crazy Place. Some are examples of Beautiful Void. Some fans may want the various mysteries to be Left Hanging. See also Send in the Search Team, when the characters do know how they got there, and now they need to find out what happened. May have an Amnesiac Hero. Compare Epiphanic Prison.

Anime & Manga
- The Big O Roger Smith is a negiotator in a domed city (implied to be a futuristic New York City) where everyone came down with a case of unexplained Laser-Guided Amnesia forty years ago. The outside world is seldom referred to, but it's implied to be largely an unexplored wasteland.
- Eden of the East: A naked man wakes up outside the White House, holding a gun. Good luck figuring out what happened, chief.
- Ergo Proxy has plenty of these, though only in individual episodes (e.g. 11, 14, 15, and 19)
- Gantz involves people dying, and then waking up in an empty apartment with several strangers. A mysterious sphere in the middle of the room commands them to go out wearing special equipment and hunt aliens.
- In Gosick, Kazuya and Victorique end up on a ship that's pretty mysterious. Although they DO know how they got there (from a ticket given to a dead woman they didn't want to let go to waste) in flashback scenes the original children sent to the ship 20 years earlier was very much an Ontological Mystery. For Victorique it's solving the mystery AGAIN in order to survive.
- Haibane Renmei: the precise nature of the town of Glie is left mysterious throughout, and although there is a way for the Haibane to leave, it's never clear where they go or how, leading to speculation among fans that Glie is an allegory for Purgatory, or that it IS Purgatory.
- Princess Tutu features a small village where an old fairy tale seems to be coming to life. The world outside the village is rarely referenced, and people seem to take the odd happenings as completely normal. There's also an old legend about the author of said fairy tale, who left the tale incomplete after his untimely demise....
- Gargantia on the Verdurous Planet: A teenage boy has been fighting a brutal race of space mollusks for literally his whole life, when he finds himself flung through a wormhole to Earth...which is now largely flooded and was thought to be uninhabitable. After some Breather Episodes of him settling into a relaxed civilian lifestyle, things start get getting foreboding.
- Urusei Yatsura: Beautiful Dreamer is built entirely around figuring out why the world keeps changing into increasingly improbable forms. It has something to do with dreams and the story of Urashima Taro...
- Attack on Titan: Humanity has spent the last century holed up within three massive Walls, protected from the Titans that appeared seemingly out of nowhere and devoured mankind to the brink of extinction. No one knows where the Titans came from, or even how the Walls that protect them were constructed — the cult that worships them claims they were a divine gift. Information on the outside world is strictly controlled by the government, and people with interest in exploring outside the Walls are labeled as heretics.
- Oh, and there are Titans in the freaking walls, too. Which is a hint as to this whole business, but still...
- Log Horizon is a more direct instance of this trope as unlike other 'trapped in an MMORPG' series's, the Elder Tale game didn't use any kind of special VR-Interface (just a standard keyboard/mouse/microphone setup), leaving the characters at a loss as to how they got transported into the game at all, or how they might get home.
- In the world of Hybrid Theory, there is a myth of Susano-o and Orochi. The fact that there are now at least three Orochis running around, each clearly the inspiration for the original myth which contained only one Orochi, means something has gone horribly wrong somewhere... Only Aaron has heard the voice of the one who set everything in motion, Chris being too dead at the time. There are many educated guesses, but no-one really has a clue as to what is going on.
- The lack of a cohesive universal backstory is bad enough on Earth where most of the societies appear 'normal' until their stories really get rolling. Washuu wakes up to find that the galaxy she's traveled end to end as a citizen of the peaceful Jurai Empire is now half-full of planets that have always been under the cruel thumb of warmongering Sailor Galaxia.
- Waking Life revolves around attempts by the protagonist to wake up from a possibly terminal dreamstate.
- Circle: Fifty people regain consciousness in a dark room, arranged in a circle around a strange-looking mechanism that kills one of them every two minutes. The subjects range in age from single digits to near-centenarian, and not one of them knows how they got where they are. They quickly figure out the premise, however—not only must one of their number die every 120 seconds, but they are the ones who determine who gets whacked next. Zany—err, paranoid hijinks ensue.
- Cube, its sequel Cube 2: Hypercube, and its prequel Cube Zero. A group of people of differing backgrounds and skill sets wake up in cubical rooms which connect to other cubical rooms (all of the rooms together forming a giant, you guessed it, cube). There are deathtraps. Have fun!
- Dark City: The protagonist wakes up with Easy Amnesia and Telekinesis in a city with no exits and where day never dawns. Oh, and there's a dead hooker in the other room.
- The first Saw movie. In later movies it is already established who is behind all of it, but the Ontological Mystery still applies to specific (groups of) characters.
- Groundhog Day is less interested in why the loops started or ended and more interested in how its protagonist responds to it. The commentary notes the story is about him changing from 'a prisoner of the time and place to the master of the time and place'.
- The Fountain portrays Real Life as an ontological trap that can only be escaped through death. The Protagonist refuses to accept this and, having eaten from the bark of the mythical tree of life at the fountain of youth, becomes doomed to outlive the rest of humanity because he's trapped in a spaceship on the edge of a dying star.
- Eden Log. A man wakes up in the middle of a dark cave, not knowing how he got there, and trying to find his way out.

Panic rises and things get violent....
- Nine Dead. The protagonists all wake up in a cell chained to a wall. Their captor tells them that one of them will die every ten minutes unless they can tell him why they are there.

- William Sleator's House of Stairs: five teenagers wake up in the titular House of Stairs. It's a giant complex of interlocking stairs and platforms, but none of the stairs lead out; they only connect to other parts of the maze.
- Issola: A couple of people our protagonist considered completely indestructible have gone missing. Not even Sethra Lavode, who very much deserves her Shrouded in Myth status, can find them by herself. She knows how to get Vlad there, and he arrives to find his two friends stuck in unbreakable, seamless chains in an empty room with no exits that appears to be on another planet. The plot hinges on figuring out how the hell the bad guys managed it, and why.
- The Helmet of Horror by Victor Pelevin. Several people wake up in rooms connected only by a chat-like computer system; each room opens into a labyrinth. Some labyrinths are real, some metaphorical, and one is accessible only through dreams.
- Dungeon series: beings from all times and spaces are brought to a nine-leveled artificial prison called the Dungeon. At no point in the series is the Dungeon's origins, masters or purpose made clear, only speculated on.
- Illium: spans three planets rather than a room. The mystery is just what has happened between our time and this imaginary far future to make the latter so bizarre. For a start, where did all those Greek gods using advanced technology and living on Mars come from? The characters on Earth in particular take their condition as a mystery to be solved and try to escape the definite confines that are set upon them even as they are able to teleport around the world freely.
- The Trial by Franz Kafka
Someone must have been telling lies about Joseph K., he knew he had done nothing wrong but, one morning, he was arrested. At the end he finds out that he is guilty of life and original sin. Once he realizes the nature of his crime, he submits willingly.
- Also by Kafka, The Castle. A surveyor is summoned to the town surrounding a tremendous castle of Obstructive Bureaucrats, and nobody is sure why; the protagonist thinks he knows who he needs to talk to so he can find out, but first he has to get an appointment with the undersecretary and convince him to give him an appointment with the regular secretary...and so on. He is inexplicably appointed two childish assistants that mostly just make fun of him. The book was never finished, so it's not clear if there ever was an ending.
- The Maze Runner Trilogy:
- The Maze Runner has the main protagonists trapped in a maze.
- The Scorch Trials, is about them trapped in the deserts of a future Earth.
- Riverworld by Philip José Farmer has apparently everyone ever born trapped between a desert and a river, with their intact memories from birth to death in our real world.

- More Than This begins as the protagonist wakes up in an abandoned town after he dies and has no idea why.

- Piers Anthony's Mercycle. The characters are not locked in a room, however, they are compelled into the task of riding bicycles under the ocean with no idea who hired them and for what purpose. It's pretty much Cube in the sea.
- Both Buffy and Angel did this in one episode each: "Tabula Rasa" for Buffy and "Spin The Bottle" for Angel. In both cases, a spell intended to affect memories went wrong and resulted in the entire main cast losing their memories. In "Tabula Rasa," they got complete Identity Amnesia. In "Spin The Bottle," they got Identity Amnesia removing all memories since their teenage years, which still complicated things because they each spent their teenage years very differently. In both cases, there were many logical but amusingly wrong deductions made about what was going on before they managed to undo the spell.
- Lost: A plane crashes on an island and weird things start happening. Beyond that, what happens is a matter of debate within the fandom because the mystery about the nature of the island is mind screwy.
- "Clues": The Enterprise crew is revived by Data after having been rendered unconscious by a Negative Space Wedgie.

- "Conundrum": The characters' memories are erased and they are left with no contact with the outside world. They need to figure out the purpose of the ship, their roles on it, and the validity of their apparent mission to destroy a planet.

- "The God Complex" with a nightmarish hotel that has a room for everyone. The Doctor even lampshades it.
The Doctor: Big day for a fan of walls!
- "Time Heist" begins with the Doctor answering the phone and then suddenly he, Clara, and two people they have never met before are in the most impregnable bank in the galaxy, having agreed to rob it on behalf of a mysterious benefactor, recorded a message to themselves explaining that they have accepted this mission, and then erased their own memories of doing so. Half the episode is them carrying out the heist, the other half is trying to figure out who orchestrated this whole thing and how they seem to have infiltrated the bank already yet still need help robbing it.
- "Heaven Sent" has the Doctor accept a transmat from an unknown source that leaves him in an enormous castle, deserted except for a Grim Reaper-like monster.
- In 1969 NBC aired The Cube, an hour long teleplay about a man trapped in a cube, wondering what was real and what wasn't. It was written and directed by Jim Henson, of all people, in a very un-Muppety not-played-for-laughs kind of way.
- The Outer Limits (1963): "The Probe," the last episode of the original series. A group of plane crash survivors find themselves in a mysterious closed environment full of lab equipment, stalked by a grotesque monster, with no idea how they got there or how to get out.

During the episode they have to fight the building itself as it turns on them, cooperate, find out why they're there and find a way out.

- Waiting for Godot: While Vladimir and Estragon know where they are and why they're there, they don't know if it's the right place or even who they're waiting for is, other than his name is Godot.
- BIONICLE. Although the characters themselves don't ask questions relating to how they, a bunch of sentient cyborgs, came to be living a primitive lifestyle on a tropical island , Word Of God has stated that this was a major source of the series' appeal in the early years, as the viewer would be curious as to how this situation came about. The Matoran were unaware that they were suffering from mass amnesia, so they were just as surprised as the viewers were when their origins were slowly revealed over the next few years of storyline.
- A genre of web games, the "escape-the-room game," is based on this. The player is trapped in a room and has to search the place for items in order to get out. It typically starts with some Easy Amnesia to explain why the player doesn't know how they got into the room. Examples include Crimson Room and its sequel Viridian Room, and Mystery Of Time And Space.
- Countdown by Access Software opens with the protagonist waking up in a mental asylum without memory.
- Myst. Interestingly, the first game has the 'who am I and where I am' set up but the the rest of the series does not because the player is expected to retain this knowledge from the first game, or get the crib notes of it. The exception is Myst V: End of Ages.
On starting the game you are confronted by a single question that follows you for the duration of the play: "What is going on?" This is in no way a bad thing. The compulsion to explore and learn more about the world in is the game.

- Planescape: Torment begins with the amnesiac Nameless One waking up in a mortuary in the otherworldly city of Sigil. Piecing together who the Nameless One is makes up most of the story.
- The Neverhood begins with our hero Klaymen trapped in a room (see above) with no information, and goes from there. Justified in that you later find out he had just been created and doesn't have any backstory.
- eXperience112 (The Experiment in America), the player is trapped in a control room with no memory how he got there. Notable in that you do not leave the room - you use its controls to manipulate another character into solving puzzles for you.

I feel uncomfortable. Where did I come from? Where was I born? The fact that I am trapped in here is the least of the mysteries plaguing my mind. Nervous. I'm nervous.
- System Shock and the sequel, System Shock 2, both begin this way. In the first game, you awaken from a coma aboard Citadel Station. In the latter game, you are brought out of cryo aboard the starship Von Braun.
