“Chicago P.D.” is back! Tune into NBC tonight for a brand new episode of the riveting police drama about the men and women of the Chicago Police Department’s District 21. District 21 is made up of two distinctly different groups: the uniformed cops who patrol the beat and go head-to-head with the city’s street crimes, and the Intelligence Unit that combats the city’s major offenses – organized crime, drug trafficking, high profile murders and beyond. The vast responsibilities that these jobs entail extend far beyond the walls of the precinct, often taking an emotional toll on personal lives of these men and women.
