Claudia Rankin's husband of one hour is murdered after they stop on an isolated road. When the police appear, to her, to be taking their time about finding the killer, Claudia changes her name and appearance and starts her own investigation. Her disappearance becomes a problem for the Missing Person Department, and they track her down. They also discover just how close she is to the solution of her husband's murder, and the location of a gang of car hijackers who operate in remote "lover's lanes."
