In North Dakota, a woman named Sally Dumont rides a horse to her farm. As Sally guides the animal to a stall in the stable, she discovers another horse, its coat stained with blood, lying on the ground inside its pen. As she kneels down next to it to investigate, Sally notices someone wearing a pair of rubber boots standing in the adjoining stall. Terrified, she makes her way to a phone and calls for help. Suddenly, the intruder looms up from behind and knocks Sally unconscious.
