Bear Grylls presents the series in which eight celebrities face a 12-day survival mission through the rainforest of Costa Rica. To stay alive, they must learn to navigate the terrain, build shelters, make fire and supplement their meagre army rations. Emilia and Laurence Fox, Max George, Dame Kelly Holmes, Jamelia, Tom Rosenthal, Vogue Williams and Mike Tindall make up the team. On the ground, Bear is assisted by expedition leaders mountain guide Meg Hine and former commando Scott Heffield. In this edition, tensions reach boiling point as the team face their toughest mission yet - how to survive and travel in water through rivers, lakes and torrential rain. With each member of the expedition team tired, wet, cold and hungry, the celebrities face their first night without army rations and have to catch their own supper. The following morning sees them take to indigenous canoes called pangas and precariously make their way to an island in the Laguna de Arenal.
