The Lost Voyage of Shackleton: The Edge of Human Endurance Part 3 of 5

In Part 3 of Shackleton's Lost Voyage, we join the stranded crew of the Imperial Trans-Antarctic Expedition of 1914, who have been stranded on the ice now for well over a year. Their ship has been crushed, starvation and madness have begun to set in, and they've been trapped by the ice and sea with no way out. In this episode, we watch as they make a desperate escape attempt while the ice splits beneath them, before heading out towards the unknown on the open sea.
