Kelly begins moonlighting as a security guard for Susan Wagner, a wealthy woman who's married to an abusive husband. But things take a turn when the husband is shot and killed, and Mrs. Wagner becomes a suspect. Meanwhile, Sipowicz is paired with the hard-nosed Detective Walker who arrests a man for a robbery and double-murder. While Detective Walker thinks he's guilty, Sipowicz thinks differently. Laura quits her job and plans to move into a position with the District Attorney's office, prosecuting narcotics. The increasingly edgy Josh Goldstein has Kelly appear at a tenant's readiness group regarding crime, and he is later killed trying to save an elderly woman from a mugging on a subway platform.

Sipowicz and Simone investigate the murder of a woman whose body was found dumped in an alley and information about the mystery woman reveals that the woman was a mail-order bride from Russia who was looking to divorce her husband. Meanwhile, Medavoy and Martinez look into the drive-by shooting on a city bus. When one of the passengers mouths off his hatred of gays, both Medavoy and Abby become angry in which Medavoy slides on a further decline when he breaks his diet and begins to show off aggressive methods against the smart-mouthed gang members they bring in for interrogation. Elsewhere, Sipowicz starts working a part-time job for the U.S. Marshall by doing garbage detail at J.F.K. airport.
