Bear Grylls: Mission Survive - Season 1 Episode 4

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. On the ground, Bear is assisted by expedition leaders mountain guide Meg Hine and former commando Scott Heffield. In this edition, the jungle has already taken its toll, with one of the group suffering from mosquito bites and another with trench foot. Bear introduces the gang to a two-mile cave system and demonstrates how to obtain vital zinc from a jungle source – in this case tarantulas! One member of the team discovers a freshly-killed pig in one of the caves and bears it back in triumph to his mates. The team are transferred by helicopter to the Pacific coast, and the largest river in Costa Rica – the Tempisque. Their mission is simple – get across the river safely. It is their last chance to impress Bear before elimination.
