CHICAGO PD PHOTOS

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.

Leading the Intelligence team is Sergeant Hank Voight, a man not against skirting the law in the pursuit of justice. Demanding and tough, only those who can take the heat survive under Voight's command. Take Detective Antonio Dawson - despite his troubled history with his boss, Dawson has ambitions of running the unit... so if that means facing off against Voight every day, he'll persevere.

From the street cops with dreams of moving up to the elite crew who are already in, "life on the job" is a daily challenge. The enormous responsibilities that come with the territory take an emotional toll, as we'll find when we follow the personal lives of our characters outside the walls of District 21.

From Emmy-winning producer Dick Wolf and the team behind "Chicago Fire" comes "Chicago PD," a gripping, character-driven new police drama about those who put it all on the line to serve and protect. One-hour drama.
