This Fierce Earth special takes viewers on a journey to one of the world's coldest and most hostile places on the planet - the Yukon Territory in Canada. The team meets people who call this frozen place their home and finds out which animals are perfectly adapted to life in a sub-zero climate. They also get first-hand experience of surviving its freezing and life threatening temperatures and Leo attempts to climb a huge wall of sheer ice.
