One of the most famous expeditions into the Arctic Ocean: In the summer of 1914, Sir Ernest Shackleton and his crew set sail on board the "Endurance". The goal of the British: to cross the Antarctic continent by dog sledge. But soon the ship is stuck in the pack ice and breaks apart. For months the crew drifts on an ice floe through the white hell, half starved and frozen to death. Shackleton is determined to bring his crew home alive. And so he sets off, in a tiny dinghy, with five of his men to fetch help. It will be a merciless race against death.
