While hundreds of thousands of tourists visit Iceland every year to witness freezing glaciers, steaming geothermal areas and huge black sand deserts, more than a thousand visitors find themselves requiring rescue. Adventurer Bear Grylls demonstrates how to make a snow cave, find water in deep tunnels, and avoid frostbite in this Arctic environment. Because finding food is a problem in this climate, Bear is forced to eat a sheep's eyeball and catch a ptarmigan (a wild bird). He also has to deal with blizzards and 50 mph winds as he attempts to reach safety.
