Award-winning Brooklyn Nine-Nine is back for it's sixth season and it promises to be the best yet! This single-camera ensemble comedy is about what happens when a talented, but carefree, detective gets a new captain with a lot to prove. Detective Jake Peralta (Samberg) is a good enough cop that he's never had to work that hard or follow the rules too closely. That is, until the precinct gets a new commanding officer, Captain Ray Holt (Braugher), who reminds this hotshot cop to respect the badge.
