Walter Bonatti is THE mountaineering legend, capable of meeting the great challenges of mountaineering: K2, Drus, G4, Matterhorn, to name a few. But the summits reached are not points of arrival, they are intermediate stages which then push him on a journey around the world, in search of himself. His exploration, starting from the vertical walls, then moved towards horizontal paths and was always expressed towards the interior space where our fears and our desires reside. Where the man, sitting alone in front of himself, must decide to surpass himself or to adapt. And Walter never complied with them, he wrote his own rules and followed them all his life, allowing himself no loopholes or shortcuts. He built himself as a mountaineer, as an explorer, as a photojournalist and as a writer, but always and only with the intention of being an uncompromising man with his hands, his muscles, his heart and his head.

In October 2010, two of France's top mountaineers, Christophe Dumarest and Yann Borgnet, fulfilled a mountaineer's dream: a six-day alpine-style ascent of Walter Bonatti's great routes through the Mont Blanc massif. Dumarest and Borgnet first climbed the north face of the Grandes Jorasses; they then climbed the Grand Capucin and the Pilier Rouge du Brouillard, completing their feat with the ascent of Mont Blanc. Their paragliding descent in Chamonix completes their feat with a touch of fun. The climbers and the director made the ethical choice not to use helicopters to shoot the film.

After the successful conquest of Everest in 1953, two Italians reach the summit of K2, the second highest mountain in the world, the next year,after careful preparation and the formation of the team of climbers, scientists, and porters.

In 1961 the southern face of the Central Pillar of Mont Blanc was still unclimbed. Two roped parties of climbers decided to come together to attempt to open a new route. Four days of violent storms caught the climbers just 80 metres from the summit. Of the seven climbers, only three returned home. One of the most intense and dramatic events in the history of climbing relives on the big screen, thanks to accounts and images of the feat.
