Grylls parachutes into the French Alps with a knife, a canteen, a cup and a flint, taking the parachute with him. He demonstrates how to survive falling into a frozen lake, how to build a snow shelter, and how to use a self arresting device to stop from plummeting into a crevasse. He also eats maggots and uses them to catch a trout. He performs a Tyrolean traverse and makes himself a pair of snow shoes out of young trees and parachute lines.
