When a conservative rural Ohio county is shaken by the discovery of the corpse of a naked woman who had been strangled in her bed, two young deputies in their twenties are assigned the responsibility of investigating. Rusty and Tina soon discover that the victim participated in cybersex and belonged to a very active swingers' community. Karen, the victim, had videotaped a foursome engaging in hot sex. That coupling took place early in the evening. Even though no faces appear in the video, the detectives catalog the participants according to their anatomical characteristics. They consider most notable the enormous erection of the man with whom Karen had paired. When an expert investigator analyzes Karen's computer, he uncovers her active participation in an online swingers' chat room.
