The mountain guide Andreas loves Marie, the hotelier's daughter whom a guest from the city, Alfred, is courting. He thinks about getting rid of his rival, who doesn't suspect anything. Alfred even hires Andreas as a guide for an ascension to the Jungfraujoch. The weather worsens during their climb and Andreas decides to give up, but Alfred is still determined to reach the summit and perishes in the attempt. When Andreas returns to the village alone, Marie accuses him of being responsible for Alfred's death and he is sentenced to ten years of prison. Many years later, Alfred's body reappears from under the glacier and a revealing note is discovered.
