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.
Intelligence investigates the shooting of a parole officer; Voight is forced to allow an outsider into the bullpen; Imani makes a difficult decision about her sister.
As the team works to bring down a drug ring, Voight builds trust with a new informant; however, it soon becomes clear she has a plan of her own.
As the team investigates the stabbing of a father with two young daughters, they begin to suspect there is more to the story than meets the eye; the FBI investigation into Roy Walton's death intensifies while Voight, Upton and Halstead feel the heat.
With the FBI closing in on the Roy Walton investigation, Voight and Halstead strategize a way out; after a city bus driver is shot by a passenger, the team investigates a possible abduction.
