Five strangers find themselves trapped in a maze-like prison. Led by cop Quentin (Maurice Dean Wint) and expert jailbreaker Rennes (Wayne Robson) they move from room to room, discovering several traps along the way. Maths student Leaven (Nicole De Boer) ascertains that the numbers on each room reveal which is safe, but this does not prevent the death of Rennes. The group are then joined by the autistic Kazan (Andrew Miller), who also has a gift for numbers. It soon becomes clear that each of them possesses the peculiar skills necessary to escape their prison, if they don't wind up dead first.
