Mont Blanc, the highest peak in the Alps, rises to 4,810 m and was first climbed on August 8, 1786. Chamonix natives Jacques Balmat and Michel Paccard set out on the afternoon of August 7 and returned victorious on the morning of the 9th, after two nights spent outdoors. This film is a staging that reconstructs this great event with all the problems it created and resolved, thus contributing to the emergence of the modern concept of mountaineering. Denis Ducroz, guide and filmmaker, immerses us in the minds and times of these two men, 224 years later.
