Both are caught by a storm, so while Milacz is waiting at the Concordia Hut, Turri returns to the valley again. On the way back, Milacz has disappeared. Suspicions turn against Turri as a murder suspect for the jealousy he might have for the beautiful Mary Dulac. To get rid of the accusation of murder, Turri sets out to find Milacs. There is a French version of the film (Les chevaliers de la montagne), shot the same year by the same team but with different actors.
