In the aftermath of a particularly horrific crime — even by NYPD standards — seven young men are found naked and murdered in one room, and a profiler is sent to the precinct to help with the investigation. Sipowicz struggles not to let his contempt for the profiler get in the way of their job and has to deal with an incompetent younger cop, but the explanation for the mass murder turns out to be pathetic and pedestrian. Meanwhile, Don makes a stupid mistake that could threaten Jill's career, and Lt. Fancy convinces the idiot that he either plays ball and stops threatening Jill's career or he spends 20 years in prison no matter what he says, and Greg and James investigate a warehouse theft that ended with a kid dead from a broken neck and leads to his dumber-than-Don brother.
