A biography of Frank Worsley who served on Shackleton's Imperial Trans-Antarctic Expedition (1914-1916) as captain of the Endurance. Leaving the Endurance when she became trapped in ice, the expedition members set off across the ice to reach Elephant Island by eventually taking to the lifeboats, one of which, the Dudley Docker, was commanded by Worsley. Shortly after reaching the Island, Shackleton took the decision to take a small party, including Worsley, on the James Caird to South Georgia in order to seek assistance. Worsley's navigational skills contributed to the success of this venture. Returning to England, he served and was twice decorated in the First World War, and was a member of Shackleton's last expedition to the Antarctic as captain of the Quest.
