The film was shot on the occasion of the Italian Geographical Expedition to Karakorum, conceived in 1926 and held in May-August 1929, under the guidance of Aimone di Savoia, duke of Spoleto. The expedition, twenty years after that of the uncle of Aimone, the Duke of Abruzzi, had as its declared objective the exploration of the Baltoro glacier area and explores the possibility of an attempt at K2. The film ends, however, hastily: the prohibitive weather conditions conditioned the production. A young geologist and geographer, Ardito Desio (head of the italian expedition to K2 in 1954), took part in the expedition.
