Six ordinary strangers awaken to find themselves in a seemingly endless maze of interlocking cubical chambers armed with lethal booby traps. Without food or water, they have only a few days to live. None of them knows how or why they’ve been imprisoned, but soon discover that each possesses a skill that could contribute to their escape. As they work together to extricate themselves from their claustrophobic cell, one thing becomes painfully clear – unless they learn to co-operate to solve the secrets of this deadly trap, none of them has very long to live.
