The mountain guide Jakob is a controversial figure. His supposed father dies and leaves behind a great heritage to the people. In the town they consider Jakob a bastard, because his parents were not married, which means that without a testament, the lands in which he lives do not belong to him. But the testament indicates that the inheritance corresponds him under a single condition, he must be the first person to climb the east face of Monte Verità. There is a French version of the film, titled 'Un de la montagne', shot the year after with the same script but with different actors and by a different director.
