Captain Ray Holt takes over Brooklyn's 99th precinct, which includes Detective Jake Peralta, a talented but carefree detective who's used to doing whatever he wants. The other employees of the 99th precinct include Detective Amy Santiago, Jake's over achieving and competitive partner; Detective Rosa Diaz, a tough and kept to herself coworker; Detective Charles Boyle, Jake's best friend who also has crush on Rosa; Detective Sergeant Terry Jeffords, who was recently taken off the field after the birth of his twin girls; and Gina Linetti, the precinct's sarcastic administrator.

District 21 of the Chicago Police Department is made up of two distinctly different groups. There are the uniformed cops who patrol the beat and go head-to-head with the city's street crimes. And there's the Intelligence Unit, the team that combats the city's major offenses - organized crime, drug trafficking, high profile murders and beyond.
