Roy thinks he’s a cowboy, which I suppose he is with the duster, Stetson and six shooters, but really he is a psychotic with a dissociative disorder, bumping off half the population of a peaceful rural town—his way of making friends with the locals. The movie opens with Roy’s first encounter with Ashley, whose severed head is destined to become his girlfriend for a time. Following the disbanding of the local police force during the crisis, the local layabouts, drunks, strippers and cable guys form a posse to track down the cowboy killer.
