Without remembering how they got there, several strangers awaken in a prison of cubic cells, some of them booby-trapped. There's onetime cop Quentin (Maurice Dean Wint), scientist Holloway (Nicky Guadagni), young math genius Leaven (Nicole de Boer), master of escapes Rennes (Wayne Robson), autistic savant Kazan (Andrew Miller) and architect Worth (David Hewlett), who might have more information on the maze than he lets on. The prisoners must use their combined skills if they are to escape.
