When the Mountaineers Make Their Cinema: Many mountaineers as part of their activity have used cameras and films to allow us to participate through images in their adventures and their emotions. Many of them have become true film professionals: Joseph Vallot, Lionel Terray, Marcel Ichac, Renè Vernadet, Jean Afanasieff, Pierre Royer, Denis Ducroz, Kurt Diemberg and many others are among the conquerors of the image of the mountain. The film depicts the passion of these men on the highest mountains in the world... behind the lens.
