NYPD Blue season 9

In the wake of the World Trade Center September 11 attacks 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 the undercover sting operation to flush out Danny's killer goes bad, there's a major gun battle in the streets of New York between police and a "made" man. Clark acts the hero, saving innocent bystanders, but takes a bullet himself and gets promoted to Detective Third Grade. When Sipowicz guns the suspect down, he becomes a very reluctant New York hero — and finally receives a well-deserved promotion to Detective First Grade. Rodriguez is furious when his seventy-year-old mother is attacked and nearly raped in her apartment. Medavoy and Jones try to solve an apparent serial-killer targeting NYU students and faculty, and uncover more than they want to about one of the victims.
