Isolated on an uninhabited island, with precarious equipment, candidates must manage to find food on their own, make a fire and build a shelter. Divided into teams, they first participate in events for the benefit of their team. After reunification, they participate in individual events. The game is also punctuated by advice, during which candidates are eliminated. The final takes place when only 4 to 5 candidates remain in the running; it consists of two events: the orienteering race and the pole event. The two finalists then appear before a jury - made up of candidates who held out until reunification - which designates the winner.
