About Naked and Marooned with Ed Stafford

Ed Stafford undertakes an extreme survival challenge as he washes up naked and alone on a desert island, Olorua, south east of Fiji. He has only his brain, bare hands and a camera to keep him alive. He'll take no food, water, clothes, knife or tools, so from the moment he arrives he is on a race to stay alive. As man can only last three days without water and three weeks without food, Ed will attempt to survive on the island physically and mentally, for 60 days.
