Detective Jake Peralta, a talented and carefree cop with the best arrest record, has never had to follow the rules too closely or work very hard. That changes when Ray Holt, a man with a lot to prove, becomes the new commanding officer of Brooklyn’s 99th precinct. As Holt reminds Peralta to respect the badge, an extremely competitive colleague - Detective Amy Santiago - starts to close in on the hotshot cop’s arrest record. Other members of the precinct include Sgt Terry Jeffords, a devoted family man, Detective Charles Boyle, a hard worker who idolizes Jake, and Rosa Diaz, a sexy-yet-intimidating detective.
