As darkness fell on May 10, 1996, a fast-moving storm of unimaginable ferocity trapped three climbing teams high on the slopes of Mount Everest. The climbers, exhausted from their summit climb, were soon lost in darkness, in a fierce blizzard, far from the safety of High Camp at...,000 feet. World-renowned climber and filmmaker David Breashears, who aided the rescue efforts back in 1996, now returns to Everest to tell the fuller story of what really happened on that legendary climb. Through remarkably intimate interviews with the climbers and Sherpas -- many who have never spoken before on American television -- Breashears sheds new light on the worst climbing tragedy in Mount Everest's history.
