To understand the difficulties of an ascent to over eight thousand metres, it is enough to remember the almost 300 victims these peaks have claimed. The Swiss alpinist Ehrart Loretan, the third alpinist in the world to have climbed all 14 8,000, and the Austrian alpinist Kurt Diemgerger cover the whole history of the conquest of the world’s 8,000, from the fifties to the present day, together with other alpinists and film directors who have climbed them. They talk about their experienced when they ventured into the death zone.

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.
