Kelly works with a Chinese detective in the investigation of the murder of an off-duty cop in Chinatown. Lt. Fancy catches Donna and Madavoy in an embrace and warns both of them about relationships in the workplace. The abused woman Sipowicz helped out turns up dead and her husband is a suspect. Meanwhile, a tough new female detective, Adrianne Lesniak, transfers into the squad because of a relationship she had with an officer at her former precinct in the Bronx and begins to work with Sipowicz on his case.

Medavoy and his wife, Marie, split up once again and she comes down to the station to have some hard words with Donna, while he decides to crash there since he cannot afford a place to live. Meanwhile, Simone and Sipowicz team up with Detective Harold Ng to probe the death of a Chinese girl whose leg has a strange marking on it which may have been self inflicted. Martinez and Lesniak look into the robbery case where a woman in a wheelchair lets a man claiming to be a policeman into her apartment, while the husband reveals a clue to Martinez that he has been seeing a prostitute on a regular basis and whose pimp might have planned the robbery. Elsewhere, Sipowicz does not want to accompany Sylvia to her latest doctor's visit, and Martinez gets an opportunity to find out where Lesniak really stands on her sexuality if she's really gay.

Diane turns to a friend at the Survivor's Network for help. A body is pulled from the water. Two Chinese men are brought in handcuffed together. The new computers arrive.
