The Ice Age has arrived, putting life in the freezer. It is at this time when great herds of Woolly Mammoths live on the plains of what will eventually be the North Sea.

Predators are everywhere, and the most dangerous of all are two species of humans that share the Ice Age environments of the mammoths.
