In the small town of Parsons, Kansas, 17-year old Greg is devastated when he loses his mother and sister in a horrific car accident caused by an escaped mental patient. To put behind him the desolation and loss he feels-and also to get rid of road rage drivers from the streets-Greg becomes a cop. He is good at it. During this time, life begins to turn around for him: he falls in love and marries his high school sweetheart and finds a renewed passion for life.The family moves to Denver and Greg takes a job as a police officer there. As Greg works the mean streets of Denver, a dark feeling inside of him begins to bubble up. This unexplainable thing, which he tries to keep buried, erupts with full force and with some deep dark strength, it now controls him. Greg becomes obsessively driven by this inner voice telling him to go out and kill. First it is road-rage drivers-then anyone whose looks he doesn't like. Unable to control the voice and the urges, he cannot help alienating his wife and daughter, who eventually leave him and move back to Kansas. Greg begins screwing up at work on the force and increasingly getting into arguments. One black night out on a "job", he ends up cornered by his own officers and is shot. Evil has been conquered...or has it all just been a test?
