Eighty-seven years after the first mountaineering ascent ever made in the Sarca Valley, this film aims to take stock of the mountaineering history of its walls, which today attract enthusiasts from all over the world. The narrative is given over to climbing scenes and interviews with the major protagonists, set against the splendid beauty of the valley. It is the story of a great laboratory where two trends, the mountaineering and the sporting, mingle, seeking via via or balance or extreme.
