📖 Plot Overview

After decades in New York, Danny Reagan relocates to Boston, where he begins working in a department that’s both unfamiliar and politically charged. He’s partnered with Detective Lena Silver, a sharp and principled officer navigating the expectations of her law enforcement lineage.

Meanwhile, Sean Reagan begins his journey as a patrol officer in the same city, determined to forge his own legacy. His relationship with his father, once strained, begins to heal through their unexpected professional connection.

At its core, Boston Blue explores intergenerational dynamics, family duty, and the evolving definition of justice—all set against the backdrop of Boston’s historic police culture.


🎬 Production & Creative Team

  • Boston Blue was given a straight-to-series order in early 2025.
  • Brandon Sonnier and Brandon Margolis serve as co-showrunners and executive producers.
  • Anthony Hemingway directed the pilot episode.
  • The series is produced by CBS Studios in collaboration with Jerry Bruckheimer Television, with Donnie Wahlberg also listed as an executive producer.

Unlike its predecessor, the new series is filmed primarily in Boston, offering a fresh aesthetic and a more cost-effective production model.


🔗 Ties to Blue Bloods

Although Boston Blue stands on its own, it remains deeply connected to the Blue Bloods universe:

  • The themes of family, loyalty, and service are still central.
  • The structure includes both procedural case-of-the-week storytelling and longer, character-driven arcs.
  • Appearances by original Blue Bloods characters, including Frank Reagan (Tom Selleck), are possible via guest spots or remote interactions.
  • Danny’s old-school New York mindset is expected to clash—and blend—with Boston’s culture, offering humor, tension, and growth.
