Boston Blue

NYPD detective Danny Reagan teams up with Boston detective Lena Silver to investigate a deadly fire at a tech company. As they dig deeper, they uncover a complex web of secrets involving facial-recognition technology.

Lena and Danny are pulled into a high-stakes murder investigation when a whistleblower tied to one of Mae's court cases is found dead; Jonah and Sean prepare for their first official day on the job.

A wharf corpse leads Lena and Danny to work a drug case with her ex-partner Rodgers. Meanwhile, Jonah and Sean track a scavenger hunt-linked disappearance, and Sarah and Mae deal with court and home issues.

While the Silvers mark Ben's Yahrzeit, Lena and Danny probe a shopkeeper's murder, Sarah handles a hostage situation, and Mae wrestles with a legal choice.

Danny and Lena investigate a murder linked to a notorious Boston cold case; a separate shooting incident creates Silver family conflict over responsibility and child-rearing.
