Watch VoirFilms. Terray. This name sounds like a challenge and evokes deep respect in the memory of every mountaineer. For all, Lionel Terray remains forever the "Conqueror of the useless", the example of a generous and mature mountaineer, far from any egocentrism and any ambition. Not only a pioneer and witness to the history of mountaineering, Terray is also remembered as a man and a master more than an athlete. Forty years after the tragic death of this extraordinary mountaineer and guide, who liked to think of himself as a "simple mountaineer", his former friends and the youngest generation of mountaineers come together in this film to celebrate and remember his legacy.
