This film is about a couple working on an illustrated book about famous serials killers, while unknowingly carrying a serial killer (the antagonist) and his girlfriend with them. Early in the film, it is mentioned on two occasions that a female serial killer was raped by her father as a child. Throughout the film, the antagonist acts increasingly threatening towards one of the female characters. When they stop in a motel, he watches her getting dressed until she notices, and then sneaks into her room, pretending to help her with her luggage. Nothing further happens. The antagonist's girlfriend explains on two occasions that his boyfriend is abusive, stating among other things that he whips her "when [she is] bad". She then reveals that she feels safe with him because she was raped by three boys, who beat her and sent her to the hospital for four months when she was 13. During a bar scene, a man grabbs a waitress, who rebuffs him. The main male character, fascinated with serial killers, plays a real audio tape of a woman who was kidnapped by one: we hear her crying, begging for her life, screaming, and then presumably being killed. He listens to this despite his girlfriend being distressed by the behaviour of the antagonist (a serial killer himself). The maim male character's girlfriend then takes photographs of the other couple having sex without their knowledge. When the antagonist notices it, he gets aroused and ignores his girlfriend saying that he is hurting her. At a gas station, the antagonist violently grabs the main character's girlfriend when she discovers that he is indeed a killer. After that, the antagonist takes them all as hostages and ends up killing his own girlfriend and taking the other woman as his "new girlfriend". He brings her to a secluded place to rape her: he fondles her breasts and bottoms while she stays petrified. She then stabs him but he pins her down on a bed and handcuffs her before raping her off-screen. She is shown the morning after, traumatized.
