Bear Grylls presents the series in which a group of 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. On the ground, Bear is assisted by expedition leaders mountain guide Meg Hine and former commando Scott Heffield. In this penultimate edition of their journey, the four-strong celebrity expedition team must find and eat the fruits of the forest, survive another stormy night and face their most extreme challenge yet - crossing a 200 feet ravine on a rope. Bear provides them with a protein boost - two dead rabbits which must be skinned, gutted and cooked over the fire. The team also have to build a camp using jungle ponchos. Before elimination, Bear sets the exhausted team another survival challenge - creating fire from a pile of bamboo poles using only knives and flints. Which three celebrities will make it into the final?
