Generations of one family all in the NYPD, from the normal street cop all the way to the commissionar. All with their own issues while on the police force with Donnie Wahlberg (Yes the brother of Mark Wahlberg) as the troubled detective who breaks the rules to get the job done. This show turned out to be the little gem of the season, an unexpected success and I really like it. If you are into cop shows then this is a must see, I like where its going and I like the Police Commissionar played Tom Selleck.
