Rick Hunter (Fred Dryer) is a (good) cop, who has a few things going against him. One is the fact that he, albeit unintentionally, injures his partners, which that not too many cops want to be his partner. Another is that his captain has it in for him. And the fact, that some of the people in his family are mobsters. Hunter teams up with Dee Dee McCall (Stefanie Kramer), another cop, whom the other cops don't like. But nevertheless, they prove to be quite a formidable duo. As stated Hunter's captains during the first season had it in for him, but during the second season, Hunter's new Captain, Wyler (Bruce Davison) did not have a grudge against Hunter but liked to do things by the book which Hunter sometimes didn't do. And during the third season, his new Captain, Charles Devane (Charles Hallahan) got along well with Hunter and McCall. After six seasons, Stepfanie Kramer left the show. During the seventh season, Hunter and Devane were transfered to the Metro Division and were joined by Joanne Molenski. Eventually Darlanne Fluegel who played Molenski left and was replaced by Chris Novack (Lauren Lane).
