Plot Summary

Lucien Berardini and Edmond Denis are two mountaineers who took part in the French expedition to Aconcagua (Andes Mountains) in 1954. Both suffered severe frostbite to their fingers and toes, and three years later, they set out to climb the Aiguille du Géant, a legendary route in the Mont Blanc massif. The camera closely follows the efforts of the roped party, an example of strength and self-sacrifice, until their victorious arrival at the summit.
