The creature is a Woolly Mammoth. It is 10,000 BC and the hunt is on. It is a time of fantastic change on earth; early humans are just beginning to inhabit North America and great climate fluctuations swing the world back into a mini-Ice Age. Many mega fauna are suddenly becoming extinct, like the sabre-toothed cat, the giant ground sloth, the camel and the woolly mammoth.

What is causing these sudden changes? Could it be over hunting, a mysterious disease or possibly even a meteor? What species cope and adapt? How does man survive?

In a forensic investigation, we will travel with scientists to major mammoth and early human archaeological sites in North America and uncover fossilized bones, ancient homes and weapons of stone.
