A film documenting the first ascent of Everest without supplementary oxygen Above 8,000 metres in the Himalaya there is only a fraction of the oxygen at sea-level. Climbers suffer sickness and headaches and risk life threatening oedemas. Just taking a step needs a tremendous effort. It's know as the Death Zone. Everest Unmasked follows Italian and Austrian mountaineers Reinhold Messner and Peter Habeler through the Khumbu icefall into the Western Cwm then up to the South Col and Summit. They face all these dangers and more when they make their historic ascent.

An amazing film directed and filmed by Leo Dickinson with and supported by the legendary Welsh climber Eric Jones. It also traces the history - both tragic and triumphant of previous attempts on the mountain including Mallory and Irvine's disappearance in 1924 and Hillary and Tensing's success in 1953.
