Chicago P.D. is an American police procedural television drama series developed by Michael Brandt and Derek Haas as a spin-off from Chicago Fire and shot entirely in Chicago, which focuses on a uniformed police patrol and the Intelligence Unit that pursues the perpetrators of the city's major street offences.
From Emmy Award-winning executive producer Dick Wolf and the team behind Chicago Fire comes Chicago P.D., a riveting police drama about the men and women of the Chicago Police Department's District 21 who put it all on the line to serve and protect their community.
District 21 is made up of two distinctly different groups: the uniformed cops who patrol the beat and go head-to-head with the city's street crimes and the Intelligence Unit that combats the city's major offenses - organised crime, drug trafficking, high profile murders and beyond.
The vast responsibilities that these jobs entail extend far beyond the walls of the precinct, often taking an emotional toll on personal lives of these men and women.
At the helm of the Intelligence Unit is Sergeant Hank Voight (Jason Beghe), a man not against crossing legal and ethical lines to ensure the safety and security of the city he loves. It's not unknown for him to be an ally one minute and the worst enemy the next.
Working hand-in-hand with Voight is Detective Antonio Dawson (Jon Seda). More levelheaded and honest than his counterpart, Antonio put his reservations about Voight aside to help the Intelligence Unit track down Chicago's most dangerous criminals while acting as a role model for the younger officers.
Rising through the ranks in the Intelligence Unit is Jay Halstead (Jesse Lee Soffer), a brash young detective who earned his spot on the team with the aid of Antonio's endorsement.
Halstead's partner is tough, no-nonsense Detective Erin Lindsay (Sophia Bush). Lindsay grew up on the street but was lifted to a better life when Voight took her in as a teenager. Halstead and Lindsay's close working relationship may be shifting into something more personal but won't if Voight has anything to do with it.
The precinct also includes Alvin Olinsky (Elias Koteas), an experienced undercover detective and confidant for Voight; Kyle Ruzek (Patrick John Flueger), a quick-witted cadet plucked from the police academy to join Olinsky on undercover assignments; Kevin Atwater (LaRoyce Hawkins), a charismatic uniformed patrolman who loves to throw a great party; Kim Burgess (Marina Squerciati), a uniformed patrolman who strives to one day become a part of the elite Intelligence Unit; and Sheldon Jin (Archie Kao), the neat and meticulous detective in charge of surveillance and tech ops.
In the Season 4 premiere, "The Silos": Intelligence investigates a gruesome case. Upon further examination, it appears the victim was wearing a CPD-issued wire at the time of his death.
Meanwhile, Burgess meets her new partner, Julie Tay (guest star Li Jun Li), who came from one of the worst assignments in the city.
Together they respond to their first call, and Tay shares details of her past.
Additionally, Commander Crowley (guest star Barbara Eve Harris) confronts Lindsay about why she and Voight were at that location on the night that Intelligence pursued Justin's killer.
In addition to Wolf, executive producers include Matt Olmstead (Chicago Fire, Breakout Kings, Prison Break), Peter Jankowski (the Law & Order brand), Michael Brandt (Chicago Fire, 3:10 to Yuma), Derek Haas (Chicago Fire, 3:10 to Yuma), Danielle Gelber (Chicago Fire) and Mark Tinker.
Chicago P.D. is produced by Wolf Films in association with Universal Television.
Season 4 originally aired on Universal TV in a double bill on Wednesdays at 20h00. After four weeks this changed to single episodes at 20h50, beginning with Episode 9 on 17 February, 2021.
