A multi-generational Irish-American family in New York City navigates the personal and professional tensions that arise from their deep ties to law enforcement, with the patriarch serving as police commissioner and his family members working across the NYPD and district attorney's office. The series follows their individual cases and moral dilemmas whilst also depicting the family's regular Sunday dinners, which serve as a forum for debate about justice, policing, and values. Loyalties are frequently tested as the characters must balance institutional duty with personal conscience and family solidarity.
