Recreation of the historical ascent of the southwest pillar of the Drus (the Bonatti Pillar), in the Mont Blanc Massif, by Walter Bonatti in 1955. A 800 meters high vertical wall that Bonatti did solo over the course of six days with provisions for only three days. The hunger; the thirst; the discouragement that he took when he was stuck on the wall without being able to climb or descend; and the way he got out of this dramatic condition: that's the subject of the film and the story of this exceptional climbing. In the film, the notorious swiss alpinist Michel Vaucher plays the role of Bonatti.
