Lt. Fancy insists to a reluctant Larson that he take a drug test and when it comes back positive of methamphetamine use, he is fired. One of Detective Mike Roberts' informants/girlfriends comes to the precinct and causes trouble for him, especially when she later turns up dead, and Roberts becomes a suspect. Although Roberts ends up being cleared, his reputation is ruined and he decides to quit the police force. Meanwhile, Sylvia has trouble getting through to Sipowicz to give their relationship another try. Also, Laura appeals to Kelly to help her re-examine a case she is prosecuting of the alleged murder of an abusive man by his wife, in which Martinez and Medavoy investigate one witness and discover some conflicting facts in the case.

Lesniak deals with a perpetrator and his "high priced lawyer and shrink" when he repeats the offense. Meanwhile, Detective Solomon uses a fast pull to take a possible serial killer case away from Simone after he brings in a possible suspect. One of Fancy's old contacts, Vinnie Greco, brings in a tip about a couple of guys looking for some heavy arms to do an armored car job and Sipowicz works with him, but Greco is working for someone else against Fancy. Sipowicz invites Andy Jr. over at his place for dinner where his son tells him that he is joining the Air Force. Also, Sipowicz proposes marriage to Sylvia and this time, she accepts.
