Blue Bloods is a drama about a multi-generational family of cops dedicated to New York City law enforcement. Frank Reagan (Tom Selleck) is the New York Chief of Police and patriarch of the Reagan brood, which he heads as diplomatically as he does the force. A source of pride and concern for Frank is his eldest son Danny (Donnie Wahlberg), a seasoned detective, family man and Iraqi War vet who on occasion uses dubious tactics to solve cases. The sole Reagan woman in the family, Erin (Bridget Moynahan), is a N.Y. Assistant D.A. and a single parent. Jamie (Will Estes) is the youngest Reagan, fresh out of Harvard Law and the family's "golden boy." However, Jamie decided to give up a lucrative future in law and follow the family tradition.
