A journey to the absolute extremes of the Himalayas in an uncompromising tribute to human endurance. Following the tragic loss of legendary alpinist Ueli Steck, his close friends – Sherpa Tenji and filmmaker Jonathan Griffith – set out to complete his final, unfinished dream: summiting Mount Everest and Mount Lhotse without supplemental oxygen. This live-action documentary transports you from the European Alps straight into the unforgiving Death Zone. Stand inside a roaring avalanche, cross bottomless glacial crevasses, and survive the gruelling ascent to gaze out from the very roof of the world.
