The Knights of the Mountain: The mountain guide and ski instructor Hans Turri has been hired by the tourist Gregory Milacz to make a route in the mountains. 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. French version of the film ‘Der sohn der weissen berge’, shot the same year by the same team but with different actors.
