Adventurer Bear Grylls heads back into the wild for the 5th season of Man vs Wild where he tackles extreme survival challenges in some of the most inhospitable places on earth. Bear goes from the extremes of Eastern Europe's frozen mountains to the searing humidity --and crocodile filled landscape -- of Northern Australia's Arnhem Land. In the Torres strait, south of Papua New Guinea, Bear is marooned on a desert island. He must find food and water, before setting to sea. The setting may seem idyllic, but these waters are patrolled by deadly jellyfish, stingrays and sharks. And Bear comes way too close for comfort with these ultimate predators.
