No one has ever survived the unassisted expedition across the Antarctic to the South Pole and back again. Explorers Justin Jones and James Castrission set out to make this world first attempt, only to realize that it’s now a race. There is already someone far more experienced on the ice, he’s tackling exactly the same record, and he has a head start. Alone in the harshest place on earth, Cas and Jonesy battle crevasses, white outs, gear failure, injury, frostbite and hypothermia as they drag 160kg across the ice. Capturing every moment of desperation and celebration on film, what results is an incredible journey into the very core of what drives some individuals to risk everything and test the boundaries of human spirit.
