July 1956: like every summer, the actor and cellist Maurice Baquet temporarily deserts the stage and the cinema studios to go to Chamonix where the mountaineer Gaston Rebuffat is waiting for him. A few days later, the two men achieved a historic first, that of the south face of the Aiguille du Midi (3,842 m), a magnificent wall rising like a rampart above the Vallée Blanche. July 1988: to pay tribute to the memory of his friend Gaston, now deceased, Maurice Baquet once again climbed this wall suspended between heaven and earth with the man who, 50 years his junior, is considered one of his best contemporary mountaineers: Christophe Profit.
