When married couple Don and his wife, Nancy, who face relationship problems and constantly argue, go on a "vacation" to a casino, a car accident takes place. Looking for help, they call the town's sheriff, who suggests they go to a certain motel and he will have the car towed the next day. At the motel, they find blood in their apartment, and a girl being savagely killed next door. The two must fight for their lives against the motel's workers and men dressed in unusual masks, but can they survive a night alone against dangerous men all by themselves with no real weapons or any other means of support?
