The Real Escape Game's story is set in the newly opened theme park Tōto London City. Attractions like the Tower Bridge Coaster, Buckingham Maze, and British Museum Theater mimic locations in real-world London. Participants in the Real Escape game visit Scotland Yard to take on the main attraction called Mystery Game. When the curtain raises on the game, and explosion goes off inside the park. The sound signals the start of a life-and-death game. The key to deactivating three bombs scattered throughout the park is a pop-up book that the "bomb demon" left behind. To stop the countdown, participants must uncover the truth in the pop-up book.
