In Chicago P.D. Season 13, Hank Voight leads the Intelligence Unit through a deeply personal and emotionally taxing season, starting with the team's reinstatement to take back a city plagued by a massive crime spike. The central narrative will focus heavily on undercover ATF agent Eva Imani and her tragic, years-long pursuit to rescue her long-lost sister Shari, who was kidnapped decades ago at age six and subjected to long-term trafficking by a man named Russ Kirby. The unit also navigates high-stakes cases ranging from airport emergencies to conspiracies in Officer Torres' old neighborhood, all while balancing heavy personal losses, including the passing of Adam Ruzek's father.
