The razor sharp razor that serves as Bobbi's murder weapon was stolen from Dr. Elliot's luxurious office in the upscale New York City neighborhood where he runs a successful psychiatric practice.
Bobby's next victim is Kate, another of Dr. Elliot's patients, who suffers from erotic fantasies so vivid that she herself cannot separate them from reality. Liz, a prostitute, accidentally witnesses the crime, immediately becoming both a target for the killer and a suspect for the police.
