When her flirtatious boss takes her for a drive to the Southeastern Ohio woodlands on a Friday afternoon to look at a real estate investment, raven-haired Bobbie Marsh realizes that this is just another attempt on his part to get her alone. Little does either of them know that this half-hour drive will quickly turn into a nightmare. After Bobbie rejects his subtle advances, Craig leaves the farmhouse and is attacked and knocked unconscious. Bobbie, watching from a window, immediately searches frantically for somewhere to hide. For the next twelve tense hours, she eludes the two vicious home invaders as they systematically check every square inch of the farmhouse. Her only means of escape is through the front door, and even if she manages to make it outside, her only chance of survival is through miles of heavily wooded, unfamiliar land. Bobbie soon faces the grim realization that she might have to become the predator if she wants to survive.
