Mammoth Journey

S1, E6: It is 30,000 years ago and Earth is in the middle of an ice age. The landscape is dominated by the mighty mammoths, living side by side with woolly rhinos, giant deer and 2 separate species of human. When the mammoths migrate south for winter they face a treacherous journey as they run the gauntlet of hunters like cave lions and the deadly Neanderthals.
