In late 1914, the charismatic and brilliant explorer Ernest Shackleton led 27 men on a voyage to cross Antarctica from one side to the other. But what should have been a successful expedition turned into a two-year nightmare of hardship and catastrophe when their vessel the Endurance was crushed in the Weddell Sea pack-ice and sunk. Stranded with no ship, no contact with the outside world and limited supplies, it would be up to the men to find their own way back to civilisation.

This is the third episode of a special mini-series that dramatically retells the extraordinary story of the 1915 Endurance Expedition.
