Giusto Gervasutti (1909-1946) was an Italian mountaineer, considered by many to be the best mountaineer of his generation and one of the greatest of the post-war era. He achieved his first feats in 1930 and revolutionized mountaineering in the Western Alps by repeating and opening routes of extreme difficulty that are still considered absolute routes today: the east face of the Grandes Jorasses (with his friend Boccalatte), the northeast spur of the Aiguille Noire de Peuterey, the north face of the Grandes Jorasses, the Gervasutti route on the Gugliermina, the east face of Mont Blanc du Tacul (where he died in 1946), among an incredible list of climbs. The film, made to mark the centenary of Giusto Gervasutti's birth, portrays a solitary and tormented mountaineer, endowed with an impeccable moral sense, an advocate of light and ethical mountaineering, always in search of an unattainable happiness.
