Bear Grylls trained as a survival expert with the British Special Forces. Follow him through some of the most unforgiving terrain in the world, as he does everything necessary to survive. Learn his survival techniques: from finding shelter and building fire, to the extremes of scaling cliffs and eating (or drinking) the unimaginable.
Bear brings along actor Jake Gyllenhaal, to test how he measures up to unpredictable and unforgiving Mother Nature. Jake will go where Bear goes and eat whatever Bear eats, if he's going to cope with some of the worst conditions known to man.
