More than two million years ago the earth plunged into a deep freeze. Vast ice sheets formed in the north - sometimes two miles thick - and shaped life around the globe.
But now, something is happening to the mountains of ice - the world is warming… and life is beginning to change.
With stories unfolding in both Southern California and the frozen tundra that was the European continent, follow a family of Saber Cats as they hunt for their very survival.
Experience the epic battles of Dire Wolves, Mammoths, Woolly Rhinoceroses, and Giant Sloths, all struggling for survival in the epoch of the ice age.
