This beautifully shot four-part series offers a truly unique opportunity to follow the lives of Royal Navy and British Antarctic Survey personnel on and off the ship during their four-month mission to Antarctica. Follow Endurance s small party of Royal Marines as they attempt to retrace explorer Sir Ernest Shackleton s epic journey across the island of South Georgia. Experience the thrill of breaking through the ice of the Erebus and Terror Gulf for the first time. Fly in the ship s Lynx helicopters over the icy seas and towering mountains of Antarctica. Face the crew s greatest challenge as they battle to save their ship in the stormy waters off Cape Horn. It will be the trip of a lifetime.
