It's not a good idea to bring your work home, but for Police Commissioner Frank Reagan (Tom Selleck), that's just not possible. Join the Reagan family for the second season of Blue Bloods, with 22 riveting episodes full of intense drama. Oldest son Danny (Donnie Wahlberg) is a detective who is suspended when he shoots an off-duty officer, and later must face off against his sister, Assistant D.A. Erin (Bridget Moynahan), during a trial. Frank's youngest son Jamie's (Will Estes) first case involves the Cavazerre crime family. And Frank faces a crisis of conscience when Erin reopens the case of a convicted rapist he arrested 18 years earlier, and uses DNA evidence to prove that he was innocent.
