May 25, 1996 - Bruce Herrod, a South African mountaineer reached the summit of Everest at 5 p.m. On the radio, we urge him to come down as soon as possible because the descent is dangerous in the middle of the night. A few hours later, no news from him. From this South African expedition which turned into a fiasco and another expedition carried out in parallel, the testimonies of the members of these expeditions show to what extent the thirst for climbing to the top of certain mountaineers, combined with the lack of oxygen , can alter the lucidity of climbers to the point of changing their relationship to death and thus lead them to neglect other expedition members in order to ensure their victory or save their own life.
