Based on the story of Ernest Shackleton?s failed attempt to cross the Antarctic continent from one coast to the other via the South Pole. Their ship, The Endurance, got stuck in ice and the men had to make their way to the wilderness of Elephant Island.
From there it turns into one of the greatest rescue stories of all time. Shackleton took 5 other men, included navigator Frank Worsley, in a small lifeboat, called the James Caird. Their task was as follows:
?to travel to the nearest inhabited place which was the whaling station back on South Georgia, some 800 miles distant and across the most stormy stretch of ocean in the world. They expected to encounter waves that were 50 feet from tip to trough "Cape Horn Rollers" in a 22 foot long boat. Their navigation was by a sextant and a chronometer of unknown accuracy, they were dependent on sightings of the sun that could sometimes not be seen for weeks in the overcast weather so characteristic of these latitudes.?
Somehow they made it to South Georgia, crossed a mountain range to get to the whaling station and raised the alarm. All the men on Elephant Island were then rescued. There was no loss of life.
