A riveting police play about the women and men of the Chicago Police Department's District 21 who put it all online to serve and safeguard their community. District 21 is made up of just two distinctly different groups: the uniformed cops that patrol the beat and go head-to-head with the town's street crimes and also the Intelligence Unit that combats the town's major offenses - coordinated crime, drug trafficking, higher profile murders and also beyond.
