The most legendary 'sequence' ever achieved by a mountaineer: on 12 and 13 March 1987, in 40 hours, 26-year-old Christophe Profit managed to climb three of the highest north faces in the Alps, in winter: Grandes Jorasses, Eiger, and Matterhorn. But over and above this 'coverage' of the feat, we discover the wings, the story behind the project, the peaks and troughs of the preparations for it, and the personality of the man behind the climbs, a dancer on sheer rock faces, focusing all the energy and reflexes of life itself in his fingertips.

"Les Compagnons Du Vide" (The Companions of the Void) is a documentary made in 1989 by Claude Andrieux and Gilles Chappaz, broadcast in two parts on the FR3 program "Montagne." The film explores the history of the mountain guide profession through portraits of mountain guides, showcasing the diversity of this high-risk occupation. It also delves into the intimate relationship between the climbing team and the client, using the example of prestigious guides. The documentary follows these teams on major climbs around Chamonix, on Mont Blanc, and on La Meije in the Écrins massif.
