Whilst on a scientific expedition, Russian scientists discover hundreds of oil drums abandoned on an isolated island. The answer to why they're here lies at the end of a dark and twisting tale. Secrets In The Ice series 3 goes to the most remote, cold, and inhospitable places on the planet to reveal great mysteries that were once 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. It explores how and why these secrets ended up in the most desolate and distant corners of the planet and contemplates what may still be concealed in the frozen depths.
