Based on the “Blue Bloods” season 9 episode 4 synopsis released by CBS, the Reagans will be in the middle of the scrum when New York gets hit by a major blackout. The police officers under Frank's (Tom Selleck) command have to handle the ensuing chaos now that one of the hallmarks of civilization has been taken away from the city.

According to the summary, the blackout also reveals to Frank some unsavory details about his own department. How this will manifest in the episode has yet to be revealed but fans can potentially expect police officers with criminal connections or ill intentions to rise out of the woodwork as the blackout extends its shadow over New York in “Blue Bloods” season 9 episode 4.

For fans of Jamco, Jamie (Will Estes) and Eddie (Vanessa Ray) continue to have challenges being engaged while still riding with each other as partners on the beat.
