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.

An eager young officer assigned to one of Chicago's most dangerous districts catches a case that Intelligence has an eye on.

A tip from a former C.I. leads Intelligence to a gruesome discovery; Voight becomes increasingly skeptical of Charlie Boyden's motives.

A significant turning point in Atwater's life prompts him to make a decision about his future.

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.
