WWII Warship Wreckage

Visits to the most remote, cold and inhospitable places on the planet to reveal great mysteries that have been frozen in time. This edition features a giant naval vessel located on the bottom of the Norwegian Sea and an ancient reptile-like creature found in the permafrost of Canada's Arctic. In Scotland, archaeologists are drawn to a strange, figure-eight shaped ditch, while an Antarctic research base finds itself suddenly surrounded by blood-soaked snow.
