Plot Synopsis

The Reagans are a multi-generational family dedicated to New York City law enforcement. Frank is the NYC Chief of Police who runs his department as diplomatically as he runs his family, even when dealing with the politics that plagued his unapologetically bold father, Henry, during his stint as Chief. Frank's eldest son Danny is a family man married to Linda, a seasoned detective with Jackie as his partner, and an Iraqi War vet who occasionally uses dubious tactics to solve cases. Erin is a newly single parent to daughter Nicky and a NYC Assistant D.A., who also serves as the legal compass for her siblings and father. Jamie is the youngest Reagan, fresh out of Harvard Law and the family's golden boy, but he gives up a lucrative future in law to be a cop who is part of a clandestine police investigation even his father knows nothing about.
