Fearless Nepali high altitude climber Nimsdai Purja embarks on a seemingly impossible quest to summit all of the world's 14 highest peaks with an altitude greater than 8000m (called eight-thousanders) in seven months, breaking by far the previous 7 years record. He named his adventure 'Project Possible.'

Between the 1920s and the 1960s the world's great powers sent vast military-style expeditions to conquer the peaks of the Himalayas, with Everest at their head. This was a great game played - camera in hand - by Imperial Britain, Nazi Germany and superpower America. As a result, Himalayan mountaineering's most iconic, epic and tragic moments didn't just go down in history, but were caught on film - from the deaths of Mallory and Irvine on Everest in 1924, to Everest's final conquest in 1953 by Hillary and Tensing. Using footage never before seen on British television, this is the story how of how film-makers turned the great peaks into great propaganda.
