Synopsis
Hunter is an American police drama television series created by Frank Lupo, and starring Fred Dryer as Sgt. Rick Hunter and Stepfanie Kramer as Sgt. Dee Dee McCall, which ran on NBC from 1984 to 1991. However, Kramer left after the sixth season to pursue other acting and musical opportunities. In the seventh season, Hunter partnered with two different women officers. The titular character, Sgt.

The show's main characters, Hunter and McCall, resolve many of their cases by shooting dead the perpetrators. The show's executive producer during the first season was Stephen J. Cannell, whose company produced the series.
