Bear Grylls heads for the icy wastes of the Arctic Circle, where he tackles frozen waterfalls, hunts wild reindeer and battles against some of the coldest conditions on the planet. Using his parachute as an improvised kite he crosses a vast frozen lake, and then plunges neck deep into a frozen river. When he finally makes the safety of the coast his adventure is far from over, he must make a raft from bits of washed up debris to reach the outer islands of the huge fjord. There his signal fire can be seen by fishing trawlers using the shipping lanes.
