An enormous prison, abandoned in the desert, a very dangerous game, and eight residents who have the same goal: escape from that terrifying place. After many years, the prison of Elefteria (renamed Súpermax), reopens its doors when a television network converts it into the stage of a reality show. The programme will test the limits of eight contestants, as well as challenge their physical and psychological endurance. The prize? Escape from a scary adventure where death lurks everywhere.
