On 3 July 1953, Innsbruck’s Hermann Buhl achieves a coup: In a 41-hour ascent, he becomes the first person to climb an 8000 metre peak solo and without oxygen: Nanga Parbat. Mountaineering star Alexander Huber meets people who were closely associated with the alpine legend, such as Buhl’s daughters, the alpinist Gerlinde Kaltenbrunner and Buhl’s climbing companion Kurt Diemberger, who witnessed his fatal fall. Their conversations, interspersed with riveting re-enacted scenes, provide an insight into the life of an extraordinary personality.
