The story of the 1914-1916 Antarctic exploration mission of Sir Ernest Shackleton. The ship sails south, breaking the ice, and ultimately getting trapped by the fast-changing weather. The ship breaks up in the ice, and while 22 men and 70 dogs wait on Elephant Island, Shackleton and a crew of five take a 20-foot lifeboat 800 miles to South Georgia Island to mount a rescue mission. We also get a good look at the exotic animals of the region, particularly the penguins.
