NBC’s Epic 3-Part Series Crossover: Release Date and Story Officially Unveiled
A three-show investigation
The crossover brings together characters from Chicago Fire, Chicago Med and Chicago P.D. Its central case concerns a suspect tied to the death of a patient at Chicago Med, according to the official description.
NBC set the event for Wednesday, January 13, 2027. The three-part story will air from 8 p.m. to 11 p.m. ET, with Peacock streaming it the next day. It marks the sixth crossover among the three series and their third consecutive annual crossover.
How the crossovers began
The first One Chicago crossover, excluding backdoor pilots, paired Chicago Fire and Chicago P.D. on April 29 and 30, 2014. Its story involved an explosion at Chicago Med, a year before the medical drama premiered.
The first crossover involving all three shows aired January 5 and 6, 2016. On October 3, 2018, the franchise staged its first same-night crossover among Chicago Fire, Chicago P.D. and Chicago Med. The 2026 event followed Firehouse 51 responding to a passenger jet that went silent midair, before the teams uncovered a wider mystery.
Shows draw strong audiences
Chicago Fire season 15, Chicago P.D. season 13 and Chicago Med season 11 premiered October 7. Variety reported that they were NBC’s top three shows of the new season.
Chicago Fire recently marked its 300th episode with original cast member Joe Miñoso leaving the series. Chicago Med is set to bring Colin O’Donnell back as Dr. Connor Rhoades in December, his first appearance since leaving the main cast in season 5. Chicago P.D. added Naiqui Macabroad as Officer Donovan “Penny” Watts.
The wider One Chicago universe
Chicago Justice also belongs to the franchise, though it lasted only one season in 2017. One Chicago shares a universe with Dick Wolf’s Law & Order franchise, whose flagship series and Law & Order: Special Victims Unit have had crossover stories with the Chicago shows.
Wolf also created CBS’s FBI franchise, which includes FBI and CIA. The new One Chicago event will bring the three continuing Chicago series together for another shared case.
