One of the most fabulous “combinations” of climbs ever achieved by a mountaineer: on March 12 and 13, 1987, Christophe Profit, 25, succeeded in his attempt to climb the three toughest north faces in the Alps, in 40 hours: the Grandes Jorasses, the Eiger, and the Matterhorn. But beyond the coverage of this feat, we discover the sidelines, the story behind the project, the ups and downs of its preparation, 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.
