US drama series following a family of New York cops headed by Frank Reagan (Tom Selleck). As well as the head of the family, Frank is the New York City Police Commissioner, following in the footsteps of his father, Henry (Len Cariou). Frank's children also share his passion for law and order: Danny (Donnie Wahlberg) is an NYC detective whose enthusiasm for justice often sees him bend the law himself, while Erin (Bridget Moynahan) works in the District Attorney's office. Frank's youngest child Jamie (Will Estes) is perhaps his favourite, but when Jamie enters the law and finds himself working on an investigation so secret even his father knows little about it, the celebrated name of the family in New York law and order circles could be threatened.
