The series follows the Irish-American Reagan family of police officers with the New York City Police Department (NYPD). Francis "Frank" Reagan (Tom Selleck) is the Police Commissioner. He was a U.S. Marine and a Vietnam veteran before he joined the NYPD. He is a widower whose son Joe died in the line of duty, leaving him three remaining adult children—Danny, Erin, and Jamie.

Danny (Donnie Wahlberg) is a top NYPD detective, holding the rank of Detective First Grade, but is sometimes hard-nosed and does not always go by the book. Danny is also a Marine veteran, having served in the Iraq War. Danny's partner is Detective First Grade Jackie Curatola (Jennifer Esposito). Erin (Bridget Moynahan) is an assistant district attorney in Manhattan who prosecutes many of the criminals Danny arrests. Jamie (Will Estes), Frank's youngest child, is a recent graduate of Harvard Law School and is a rookie officer on the police force after graduating from the police academy. Henry (Len Cariou) is Frank's father and the former NYPD police commissioner, now retired. Henry served in the United States Marine Corps during the Korean War. Henry often provides advice to his son and grandchildren. The family is close-knit; each episode includes a scene wherein they all have dinner together with their spouses and children and discuss their current cases.

Frank's middle son, Joseph, was an NYPD police detective who died in the line of duty. Joe was involved with the Federal Bureau of Investigation (FBI) investigating a group of dirty cops, who were operating within a fraternal organization called the "Blue Templar". Joe was murdered by these dirty cops when his covert investigation into their corruption was getting too close.
