Bobby Simone, a widower and homing pigeon breeder, joins the squad as Kelly's replacement. Simone's first assignment is to help Sipowicz in the investigation of the hit on a mobster's son, where a stray bullet also hit an elderly woman in her apartment. Meanwhile, Lesniak tries to help a woman who's worried that her husband is molesting their daughter, and an over-the-edge Abruzzo pulls his gun and threatens Lesniak in the squad room for leaving him.

Medavoy decides to go on a diet and has a hard time getting started on it. Meanwhile, Sipowicz has problems with his work, his baby son's illness and Sylvia deciding to return to work at the D.A.'s office. Simone proposes marriage to Russell, but she is hesitant to give him an answer. Martinez has eyes for Gina Colon the new administrative aide for the anti-crime unit since Lesniak has been transferred from the squad to another precinct, thus leaving the 15th for good. But none of the men are turned on by Donna's latest replacement, a frumpy lady named Gerri Turner as the PAA for the squad but she has a strong interest in Sipowicz. A body in a trunk of a car is inadvertently moved from the nearby 13th precinct into the 15th's jurisdiction. Elsewhere, Simone inherits an apartment building from a recently deceased woman and the woman's son, Henry, is upset at the situation.
