One Reagan is in some serious trouble in the Blue Bloods Season 11 premiere.

But fortunately, there's another member of the family with the force now who can pitch in to help. In "Triumph Over Trauma," Danny (Donnie Wahlberg) and Baez (Marisa Ramirez) go missing while looking for a killer, and Joe Hill (Will Hochman), the son of the late Joe Reagan, joins Jamie (Will Estes) in looking for them.
