Three young climbers – Bruno, Emma, and Pippo – set-off to climb a dangerous mountain using a perilous route, which hasn’t been successfully conquered in over 50 years. Two legendary climbers, Boldrin and Jugovic, who disappeared here long ago under opaque circumstances, had named this route Dark Vertigo. Ignoring bad omens, the three friends attempt the impossible, but after proceeding a short distance, they find themselves enveloped in dense fog. And with the fog comes horror. The mountain, often violated, takes revenge.
