Eleven mountaineers who set milestones in the history of alpine climbing: Hans Dülfer and Paul Preuss, the greatest pioneers of rock climbing despite their early deaths; Willo Welzenbach, intellectual and pioneer of modern ice climbing; Louis Lachenal, the "sprinter" on the mountain and a personality who went beyond all norms; Diether Marchart, who succeeded in making the first solo ascent of the Matterhorn North Face at the age of 19; Toni Kinshofer, who amazed with his outstanding ability in rock and ice despite his amputations; Günther Messner, who tried to step out of the shadow of his big brother, Reinhold; Heini Holzer, small in stature, but a giant in the mountains; Xaver Bongard with his technical solos and first base jumps; Alison Hargreaves, who desperately tried to reconcile her duties as a mother of two small children with her urge for extreme tours.
