[3] The films tells the true story of explorer Sir Ernest Shackleton (Kenneth Branagh) and his 1914 Antarctic expedition on the ship Endurance.

Shackleton's goal is to drive dog sled teams from one side of Antarctica to the other, which would make Britain the first nation to undertake such a trans-continental journey.

He undertakes an epic journey across the ice, followed by 800 miles of the Southern Ocean and then an uncharted mountain range on South Georgia Island.
