After a woman in a troubled marriage, whom Hooker meets in a bar, is fatally stabbed, he notices a similarity with three other cases, and a pattern emerges that all of the women had phoned in to a relationship therapist's call-in radio show before they were murdered. Convinced that the connection to the radio station is the key to the killings, he tries to persuade the show's therapist to help him track down the killer, but she is very reluctant, worrying that the bad publicity will stop callers to her show... During the investigation, Stacy and Corrigan rescue a young baby and it's mother from a brutal attack stirs feelings between them.
