Three mountaineers, including a woman, climb the l'Aiguille du Moine, in the Mont Blanc Massif departing from the Couvercle Shelter. Facing walls that are sometimes rocky and sometimes snowy, they end up reaching the summit, which rises to 3412 meters high. One of the mountain guides in the film is Hermann Perren, who also participated in the another film by René Moreau: A la conquête des cimes (1927).
