Grylls parachutes into the extreme landscape of Iceland, the site of vicious blizzard, 50 mph (80 km/h) winds, icy glacial waters, boiling hot mud and volcanic springs. He demonstrates how to make a snow cave, find water in volcanic underground tunnels and avoid frostbite. To find food in this subarctic environment, Grylls scavenges a sheep for its eyeballs and mutton fat, and catches a ptarmigan. He demonstrates with his shoelaces the boiling of the eyeballs and mutton in the geysers, to save digestion energy and disinfect the scavenged food.
