John Kelly and Andy Sipowicz are detectives in the 15th squad. Sipowicz is the elder partner but is a drunk and a threat to the partnership lasting much longer. Kelly has a genuine affection for his partner but becomes increasingly exasperated by Sipowicz's behavior. In the pilot, Sipowicz is shot, and nearly killed, by Alphonse Giardella, a gangster whom Sipowicz, while drunk, insulted badly in public. This leads to his decision to stay sober (after involuntarily drying out while in a coma) and save his job. While his partner is recuperating, Kelly is teamed up by the squad's Lieutenant, Arthur Fancy, with a young cop from Anti-Crime, James Martinez.
