Adrift on the Antarctic pack ice with no means of escape and no hope of rescue, Ernest Shackleton and his men are surely doomed.

In August 1914, Ernest Shackleton and his men set sail for Antarctica, where they plan to cross the last uncharted continent on foot. In January 1915, his ship, the Endurance, becomes locked in pack ice. Later, it sinks without a trace.

To survive, Shackleton and his crew of twenty-seven men must undertake a trial even more extreme than their planned crossing of the frozen continent. Their aim is to make it home against tremendous odds, with only lifeboats to cross the heavy seas of the South Atlantic - and the life-saving power of Shackleton's extraordinary leadership skills.
