NYPD Blue S06E06 - Danny Boy

Danny Sorenson transfers from Narcotics to the 15th Precinct's detective squad. While he and Sipowicz lead a double homicide investigation, Sorenson struggles to overcome the squad's suspicion of his techniques and intentions. Meanwhile, Costas has misgivings about the accuracy of the past conviction of a teenager and asks a reluctant Sipowicz for help, but Andy and the original detective on the case, Sgt. Dornan, don't click.
