The film narrates, also with the help of people who knew him (such as Simone Moro, his companion on his last climb), the life, mountaineering feats and very tolerant character of Anatoliy Boukreev.
This famous alpinist made more than twenty-one ascents on 8000m high mountains, without using additional oxygen, and reached the top of Everest four times. In 1996 he saved the lives of many alpinists in a group led Scott Fischer during their attempt on Everest.
The documentary is based on footage shot during his last tragic ascent of Annapurna.
