Step back in time by 40,000 years and the world is a very different place. Vast swathes of the northern hemisphere are covered by ice sheets, glaciers carve great valleys through the landscape and continents merge as sea levels fall. Hairy beasts and ferocious predators rule, while immense animals migrate across vast, unfamiliar landscapes. With unique access to excavations and state of the art forensic analysis and spectacular CGI, Ice Age Giants travels back to a land before time with Professor Alice Roberts to reveal the Ice Age through the eyes of the animals that lived there.

Ep 2 Land of the Cave-Bear - Alice ventures to the parts of the northern hemisphere, hit hardest by the cold - Europe and Siberia. High in the mountains of Transylvania, a cave sealed for thousands of years reveals grisly evidence for a fight to the death between two staving giants, a cave bear and a cave lion. Yet Alice discovers that for woolly rhinos and woolly mammoths, the Ice Age created a bounty.
