Marcel is on the eve of his 95th birthday. He trained his two sons, Claude and Yves, in the world of climbing where they are key figures. When old age came, a climbing buff, Marcel could not give up his passion. He then begins a final procession towards his last Mirror at the age of 94, accompanied by his sons. The northwest wall of the famous 450-meter Argentine Mirror (canton of Vaud, Switzerland) is the scene of Marcel's adventure, at the height of his art, a feat and a beautiful family story.
