Liam Neeson narrates this docu-drama about Sir Ernest Shackleton's ill-fated Antarctic expedition - which uses contemporary footage alongside the real footage of the expedition taken by cameraman Frank Hurley. In August 1914, Sir Ernest Shackleton, a renowned explorer, set sail with 27 men on his ship The Endurance. His plan was to be the first expedition to cross the Antarctic continent. But when the ship becomes trapped in the ice floes and frigid open ocean of the Antarctic, Shackleton decides, with many of his crew injured and weak from exposure and starvation, to take a team of his fittest men and attempt to find help. Setting out in appalling conditions with hopelessly inadequate equipment, they endured all weather and terrain and finally reached safety. Persuading a local team of his confidence that the abandoned team would still be alive, he set out again to find them and, after almost 2 years trapped on the ice, all members of the crew were finally rescued.
