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.

Voight and the team work together to uncover the truth of the Bell case before more lives are lost.

Platt finds herself challenged when a simple favor for a former recruit spirals into something far more devastating.

Upton's dogged pursuit of a missing teenage girl leads the team into a dark web of human trafficking; chief O'Neal becomes involved with the unit's investigation when it becomes evident his son, Sean, has a connection to the missing girl.

The clock is on when Ruzek witnesses a woman's kidnapping and the team races to put the pieces together; Burgess tries to connect with Ruzek outside of work, but he mysteriously distances himself from her.
