5. 100 Years of Progress

In the gripping finale, the crews of the Epsilon and Polaris confront the truth behind the Arctic phenomenon that brought them together, and face a life-changing decision about how to get home.

When a stranded Arctic research vessel transmits a call for help, the ship that comes to the rescue is not what they expected. Trapped together in a frozen limbo, two crews separated by a century must survive starvation, the elements, and paranoia to get home.

A chilling five-part supernatural thriller that blends claustrophobic survivalism, cosmic sci-fi and environmental geopolitics, set in one of the most hostile places on Earth - the Arctic tundra. Written by the writers of the award-winning drama podcast 'Up In Smoke', Cambria Bailey-Jones and Guy Larsen.
