Without knowing how they got there or why they were there, several strangers awaken in a maze of cube-like rooms, some of them containing deadly booby traps. There's tough cop Quentin (Maurice Dean Wint), doctor Holloway (Nicky Guadagni), young math whiz Leaven (Nicole de Boer), escape artist Rennes (Wayne Robson), autistic savant Kazan (Andrew Miller) and architect Worth (David Hewlett). The cube inhabitants must rely on each other's strengths if they are to have any chance to escape.
