After a hooded man open fires on their patrol car, Roman is left wounded and Burgess takes off after the shooter, briefly losing sight of him, and shoots when she relocates him turning in her direction with a glimmer of silver in his hand. No gun has been found at the crime scene and the shooter is identified as a 17-year-old honor student who will likely never walk again due to his injuries. Protests begin as the public views the case as another incidence of a police officer shooting an unarmed African American teenager. Assistant State Attorney Peter Stone (Philip Winchester), the same man who sent Voight to prison, has been assigned to help defend Burgess and conduct his own investigation under the supervision of State Attorney Mark Jefferies (Carl Weathers). Stone and his investigators Daren Okada (Ryan-James Hatanaka) and Lori Nagle (Joelle Carter) need to collect enough evidence to indict the teen and clear Burgess, but must tread with caution on this high profile case as tensions run high.
District 21 of the Chicago Police Department is made up of two distinctly different groups: The uniformed cops who patrol the beat and deal with street crimes, and the intelligence unit, the team that combats the city's major offenses, such as organized crime, drug trafficking and high-profile murders. Leading the intelligence team is Sgt. 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 Det. Antonio Dawson, for example. Despite a troubled history with his boss, Dawson has ambitions of running the unit. 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.
