Hooker is suspended when his pursuit of heroin pushers interferes with federal agents who are after the ring's supplier.

A series of young nurses are being murdered and a witness places another nurse at the scene. Hooker discovers some similarities to a previous case he had worked 6 years before, but the killer was never apprehended. It is soon discovered that the suspect may not be a woman at all, but a man dressing as a woman - specifically, a nurse.
