In 1983, three climbers became the first French people to reach the summit of Everest. Among them were expedition leader Pierre Mazeaud and a promising 25-year-old climber, Jean Afanassieff. Twenty years later, the two legends, accompanied by mountain guide Michel Pellé, retrace the steps of their exploit and make the trek from Kathmandu to the foot of the roof of the world. This is an opportunity to retrace the history of the successive assaults on Everest and to assess the current situation of a mountain that has become a victim of its own success: while Sherpas have been able to take advantage of Western enthusiasm and thus enrich themselves and equip the summit to make it more accessible, the site's attendance poses numerous problems, both human and ecological.
