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 by-standers, but takes a bullet himself. 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. Meanwhile, Rodriguez is furious when his seventy-year-old mother is mugged by a face from his past. When the Lieutenant from another precinct blows the investigation, Rodriguez has to make it personal in order to bring the thug to justice. Also, 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.
