Bear Grylls is no stranger to extremes. As one of the youngest people to climb Everest and one of the few to successfully complete the gruelling training for the French Foreign Legion, he has experienced intense cold, pain and exhaustion. But now he's up against something a bit different. Born Survivor puts Bear in situations that could happen to anybody, anytime and proves how easy it is to be caught by surprise in life and death situations. Bear Grylls tackles the deadly mangroves of Panama as he parachutes into crocodile and shark infested water in the first of this two part programme. Using vines he drops into the Camino Reale viper pits where he will face one of his biggest fears in the pitch black cavern. With no food or water he has to use what he can find for nourishment and it is the local wildlife he turns to; including longhorn beetles and crab. Bear uses his own well honed skills as well as knowledge gained from local tribes to show how to survive in such a challenging place.
