NBC Sets a Three-Part Chicago Crossover for January
Three shows from NBC's Chicago family will share one mystery on Wednesday, Jan. 13, 2027. NBC will air the three One Chicago episodes back-to-back from 8 p.m. to 11 p.m., Variety reported on Thursday.
A crossover is an episode, or group of episodes, in which characters from different shows meet in the same story. This one runs across Chicago Med, Chicago Fire and Chicago P.D. Each show gets its own part of the case, and the storyline is told over all three hours.
The mystery centres on the death of a patient at Chicago Med. The investigation turns up an unexpected suspect, and the characters from all three series work the case together.
The episodes will stream on Peacock, NBC's streaming service, the day after they air on NBC. That means viewers who miss the live broadcast can catch up the next evening.
This is the third season in a row that the franchise has run a crossover. The previous one aired in March 2026. Fans who like the shows to cross paths will have to wait about two months for the next one, and this one comes early in the new season.
Chicago Fire is now in its 15th season, Chicago Med in its 12th and Chicago P.D. in its 14th. All three are produced by Universal Television and Wolf Entertainment. Variety also reports that the season premieres of the three shows rank as NBC's top three new-season shows.
For viewers, the plan is simple. Mark the Wednesday evening, or set a reminder for Thursday on Peacock if the live hours are not possible. The three hours will tell one story from start to finish, so the three episodes are best watched in order.
