Renko gets put out when a Division homicide detective ridicules his efforts to learn who killed a 15-year-old prostitute; Furillo learns that he may be in line for a promotion to commander; LaRue and Washington have a surprise for Hunter during his annual Alligator hunt in the city sewers; and Fay asks Furillo's help with an obscene phone caller.

Furillo's chances for promotion are threatened when a city councilman is implicated in the murder of the teenage prostitute; LaRue continues to look for money for his ""saloondramat""; Fay's obscene caller breaks into her home; and Belker confronts an anti-Semitic cop just transferred to the Hill.

Furillo pushes the investigation of Councilman McAuley; LaRue's business dream comes to a bitter end; Lt. Hunter gets his chance to test out an ""urban tank"" in sniper alley.

The Hill reaches a crisis point of outraged citizenry and stampeding press coverage when Hill and Renko rescue an escaped mass murderer captured by a vigilante mob, and Belker can't stop being a cop even as he coaches Robin through labor.
