Plot Synopsis

CHICAGO PD is spinoff of CHICAGO FIRE, focusing on the two distinct groups within District 21 of the Chicago Police Department: the uniformed cops, who patrol the beat and deal with street crimes; and the intelligence unit, which combats the city's major offenses, such as organized crime. Leading the intelligence team is Sgt. Hank Voight, a man not against skirting the law in the pursuit of justice. Demanding and tough, only those who can take the heat survive under Voight's command. Voight's hand-picked group of detectives includes: Det. Antonio Dawson, who is more level-headed and by the book than his counterpart; Jay Halstead, a brash young detective, who previously saw active military duty in the Middle East; Halstead's partner, Erin Lindsay, a former bad girl who turned her life around with Voight's help; Alvin Olinsky, an experienced undercover detective and confidante for Voight; and Kyle Ruzek, a quick-witted cadet plucked from the police academy as Olinsky's partner. They're joined by tech geek Sheldon Jin and two rising young uniform cops: Kevin Atwater, a charismatic patrolman who has an active social life; and Kim Burgess, a patrol officer, who strives to one day become a part of the elite Intelligence Unit. The Season 1 finale of CHICAGO FIRE, which aired on Wednesday, May 22, 2013, introduced new characters, many of whom became part of this spinoff series. CHICAGO P.D. returned for its second season on Wednesday, September 24, 2014 at 10pm ET/PT on NBC. In the season opener, "Call It Macaroni," Voight is under close watch by Internal Affairs as the Sheldon Jin murder investigation moves forward, but he's still in complete command of the intelligence unit. A routine undercover job becomes anything but when Voight's SUV is T-boned while trailing an armored car carrying Ruzek. At District, Burgess meets her new partner, Sean Roman, and tension is high from the start. Soon she realizes there's more to his story than just a guy who transferred from another district to fill the void Atwater left after his promotion to Intelligence. After a long day, Lindsay pays a visit to someone she hasn't seen in a very long time -- her mom, Bunny. Season 3 of CHICAGO P.D. premiered on Wednesday, September 30, 2015 at 10pm ET/PT on NBC. In the season opener, "Life Is Fluid," Intelligence is in pursuit of Derek Keyes (guest star Bokeem Woodbine), number one on Chicago's Most Wanted list and heroin kingpin. Meanwhile, Halstead tries to get through to Lindsay as her downward spiral continues after her three-week absence from the unit. At District, Olinsky opens up to Platt about a secret from his past. Roman expresses his concerns to Burgess about what she's getting into by marrying Ruzek. Season 4 of CHICAGO P.D. premiered on Wednesday, September 21, 2016 at 10pm ET/PT on NBC. In the season opener, "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, 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 confronts Lindsay about why she and Voight were at that location on the night that Intelligence pursued Justin's killer. Season 5 of CHICAGO P.D. premiered on Wednesday, September 27 at 10pm ET/PT on NBC. In the season opener, "Reform," the district is in a state of change -- Lindsay has moved to New York -- and the CPD is under scrutiny about the corrupt nature of its institution. Under the watchful eye of the city, the team attempts to bust a gun deal that quickly turns dicey when innocent civilians and children get involved. Tension erupts when Chief Lugo (guest star Esai Morales) brings in Denny Woods to review the shootout, and Halstead becomes a key player in the outcome of the case. Season 6 of CHICAGO P.D. premiered on Wednesday, September 26, 2018 at 10pm ET/PT on NBC. In the season opener, "New Normal," bad heroin is causing overdoses in Chicago, and Intelligence is a man down with Voight suspended. Antonio takes charge, but Ruzek undermines his authority.
