A mountain climber from America (Warren Douglas) is obsessed by his fear of the Matterhorn, where his father had died on an ascent. Other than begging the question of why he was pursuing mountain climbing to begin with, it does serve as a starting point for the plot. He refuses to climb it as part of a rescue party, which earns him the scorn of a guide (Gilbert Roland) who is his rival for the love of a local girl (Anna Lee). He finally agrees to make the climb and, during the ascent, the guide tries to kill him.
