Meg Foster and Tyne Daly star as two very different partners on the New York City police force in the series that would go on to not only redefine the detective genre, but also become groundbreaking television in the process! In a common effort to fight crime and prove themselves to their male colleagues, Christine Cagney (Foster) and Mary Beth Lacey (Daly) become not only top-flight cops, but also the best of friends.
