Retrospective of four major peaks climbed by French expeditions: Annapurna (8078m) in 1950; Makalu (8481m) in 1955; Mustagh Tower (7273m) in 1956 and Le Jannu (7710m) in 1962. A film by Lucien Berardini and Jean-Marie Perthus with the support of the French Alpine Club and the FFME (French Mountain and Climbing Federation).

Three years after the 1959 expedition, abandoned 350m from the summit, Lionel Terray leads a new assault on Jannu, one of the most demanding peaks in the Himalayas. At the base camp, equipment and food rations are prepared. The conditions are optimal and the ascent can begin. The camera follows the progress of the mountaineers and Sherpas as closely as possible, from one high-altitude camp to another: installing fixed ropes, progressing over crevasses, in the middle of frozen towers, vertically down immense ice falls or along the edge of sharp ridges. From 7000m, oxygen bottles become essential, as the difficulty of the climb prevents acclimatization. The expedition is a total success: the majority of its members reach the 7710m summit.

"Les Coulisses De L'Exploit" was a French television program of sports information created by Jacques Goddet and Raymond Marcillac, and broadcast on RTF Television then on the first channel of the ORTF from December 13, 1961 to August 16, 1972. The principle of this program is to report on sports news but also to meet men and women performing exceptional feats. According to Raymond Marcillac: "Competitive sport is not our only field of action. It never has been. We want to discover beings whose life is enriching, exhilarating; men who have accomplished acts that can be offered to our admiration without reluctance."
