Travel back in time with popular children's presenter Andy as his latest spectacular adventures bring natural history and science to life for young viewers. Heading back to a prehistoric world he comes face to face with the dinosaurs that once ruled our planet and the Ice-Age beasts that followed in their footsteps. In the ice age 30,000 years ago, Andy treks across snow and ice with the legendary woolly mammoth. And he travels back one million years for an encounter with the biggest killer cat of all time, the sabre-toothed tiger - and even manages to meet her cubs! But he's not just taking to the land - Andy's underwater adventure takes him back 36 million years in search of the mighty Basilosaurus, a whale four times larger than a great white shark!
