Eight celebrities will be sent to live in a bunker designed to block out any light. Over five successive nights 50 infra-red cameras will follow the contestants as they get to grips with living in pitch blackness.

Ever wondered how you'd cope in prison? For seven celebrities, that fantasy becomes an unnerving reality.

A reality competition that pits nine people against each other in the ultimate battle of endurance. Nine contestants are isolated from the rest of the world - and also from each other. The players then become subjects in a series of strange and taxing experiments. They must endure challenges involving hunger, pain, sleep deprevation, mind control, and more! All for the coveted $50,000 prize. Though there are nine players in this game, the real battle lies between each contestant and his or her own self.
