NYPD Blue (season 9)

In the wake of the World Trade Center disaster and Danny's disappearance, the 15th Precinct faces a gruesome investigation when four young girls are found dead in an apartment. Sipowicz, in a black mood because his partner's whereabouts are still unknown, takes out his anger on everyone around him. While investigating the murders, Sipowicz and McDowell team up with a young narcotics officer, John Clark. When a possible lead in Danny's disappearance emerges, the trail leads right to the son of a Mafia capo. When the worst possible news is confirmed, a witness is enlisted to wear a wire as they go after the suspect. As Medavoy, Jones and McDowell learn the quadruple murder was a robbery gone bad, Sipowicz once again confronts the temptations from the past, anticipating the next day's undercover operation.

When the Lieutenant from another precinct blows the investigation, Rodriguez has to make it personal in order to bring the thug to justice.
