A woman is found shot-to-death in her shower. The person who found the body was the victim's lover--a ""Shock Radio"" host. Chris' main suspect is the host, but his alibi is that he was doing his live show at the time of the murder. While on the air, an obsessed fan calls in to admit to killing the host's lover. Meanwhile, Chris goes to talk to Melissa, who works at the same radio station.
