Visits to the most remote, cold and inhospitable places on the planet to reveal great mysteries that have been frozen in time. Merging CGI re-creations, advanced scanning technology and scientific research, the series investigates the curiosities that have been lost for millennia, or never seen before.

The Patagonian ice dragon, which isn't actually a dragon but an insect that has adapted to life on the frozen glaciers of South America's Andes Mountains, the only bug that lives on the Patagonian ice fields. Scientists believe that their bodies contain natural antifreeze, which stops their blood from turning solid amidst the bitter cold.
