The idea is a simple one: three alpinists climb in the Mont Blanc Massif. This situation brings one face to face with the dangers of the mountain: avalanches, crevasses, fog, the climbing of the rocks, roping up, etc. All of this is magnified, transcended by a remarkable and strong use of the language of cinema. One of the first films about high mountains with Roger Frison-Roche and magnificent music by Maurice Jaubert
