When an anti-environmentalist Alderman is killed during a vicious hit-and-run, Antonio and Nagel go all out to track down the driver. But instead of this being an organized hit to save the environment, it turns out the driver is a frantic mother desperate to save her kidnapped daughter. When Valdez discovers the mother was victim of a scam, the legal question becomes complicated: who is responsible for the Alderman's death? The mother trying to save her daughter? Or the perpetrators of the scam?.
Just like their brethren in the Chicago P.D., the State's Attorney's dedicated team of prosecutors and investigators navigates heated city politics and controversy head-on, while fearlessly pursuing justice. As they take on the city's high-stakes and often media-frenzied cases, they must balance public opinion, power struggles within the system, and their unwavering passion for the law. And it all starts with a gut-wrenching case when one of Chicago's finest is shot in the line of duty.
