Simone and Sipowicz get another murder case where a mild mannered professor is found decapitated in his apartment. Meanwhile, Martinez is helping out a former porno actress who is getting harassing phone calls, but Lesniak is not comfortable with the situation. Andy Jr. arrives in town with some news for Sipowicz, but he can't find the time to tell his father and finally at dinner, he explains that he has just been discharged from the Air Force and is joining the police department in Hackensack, New Jersey.

Simone, Sipowicz, Medavoy and Martinez together conduct an investigation into the death of a worker at a construction site, where more than a building is being framed and try to sort out a feud between two different unions. Meanwhile, Geri reports to Sipowicz about finding a friend of hers who has hung himself and Fancy suggests that Russell and Kirkendall conduct the investigation, which reveals the man died from kinky sex... with Geri. But the dangerously disturbed, sex-obsessed Geri will not speak to anyone about the case except for Sipowicz whom she has an obsessive crush on. Martinez stays close to Gina while she is recovering and preparing to get her stitches from her horribly scared face removed and offers him to let her stay the night with him.
