Eight celebrities embark on a 12-day expedition in the rainforest of Costa Rica, where they must learn to navigate difficult terrain, build shelters, make fire and eat the food that nature provides.

Kelly Holmes, Mike Tindall, Emilia and Laurence Fox, Max George, Jamelia, Vogue Williams and Tom Rosenthal make up the team.
