Chicago P.D.'s Intelligence Unit, led by Sgt. Hank Voight, investigates the city's most formidable offenses -- drug trafficking, organized crime, high-profile murders and other large-scale felonies. The squad -- made up of Voight, Trudy Platt, Kim Burgess, Adam Ruzek, Kevin Atwater, Jay Halstead and Hailey Upton -- is committed to protecting the city and seeking truth, but in the midst of a changing criminal justice system, the team struggles to maintain peace in the community. Voight must learn to adapt to a shifting sociopolitical climate and embrace new tactics to crack down on crime in the city he loves.

After a seemingly innocent young man is gunned down in the street, the team works to bring in the suspected culprit, but the case is more complex than it appears; the grief-stricken father is determined to do his own undercover work.

Intelligence adapts to a different style of community policing while working a kidnapping case in Chicago's Chinatown.

Voight's new Internal Affairs handler proves to be suspicious of his actions; Voight must work with his former partner from the Gang Unit; Halstead enlists Jin to help him gather more information on Lonnie Rodiger; Olinsky takes Ruzek down a peg.

Burgess and Atwater come across a gunshot victim and the only witness is Olinsky's daughter; Ruzek goes to Burgess for help with an undercover mission.
