Crossing the Ice - A journey to hell and back: James Castrission and Justin Jones, dare to not only tackle the perilous journey across Antarctica to the South Pole and return, but to do it completely unassisted – no sled dogs, no wind kites, just two men dragging their food, their shelter and themselves across 1140 kilometres of barren ice. And back again. As they battle frostbite, hypothermia, crevasses and starvation over three months of torture in the harshest place on Earth, Cas and Jonesy discover their limits, the nature of sportsmanship and the boundaries of the human spirit.
