Chicago’s firefighters, doctors and detectives are sharing one case – and one big night of television. NBC has announced a three-show One Chicago crossover bringing together Chicago Med, Chicago Fire and Chicago P.D. on Wednesday, January 13, 2027.
Taylor Kinney first revealed the date during his November 11 appearance on The Tonight Show Starring Jimmy Fallon and the date was confirmed by NBC today. The connected episodes will air in their normal tome slot, back-to-back from 7 to 10 p.m. Central, with streaming available on Peacock the following day.
The investigation begins with a patient’s death at Chicago Med and an unexpected suspect. From there, the story pulls characters from all three series into a case that spans the evening.
NBC is keeping further plot details under wraps, including the suspect’s identity and which characters will take the lead. The premise puts a medical mystery at the center of the action, giving the hospital staff, Firehouse 51 and Intelligence Unit a shared problem to unravel.
The January event marks the third consecutive season with a crossover connecting all three One Chicago shows.

The previous event aired in March 2026, beginning when Firehouse 51 responded to an airfield after a passenger jet went silent in midair. That emergency opened into a larger mystery with consequences beyond the runway.
For viewers who follow the full Wednesday lineup, the crossovers turn the franchise’s shared city into a shared story. Relationships and responsibilities that usually develop within separate workplaces collide, giving the characters reasons to work together beyond a brief guest appearance.
The event also arrives with the franchise continuing to anchor NBC’s schedule. According to the network, the season premieres of Chicago Med, Chicago Fire and Chicago P.D. rank as its top three shows of the new season.
Fire is currently in its 15th season, with a cast including Taylor Kinney, Miranda Rae Mayo, David Eigenberg, Joe Miñoso, Christian Stolte, Hanako Greensmith, Jocelyn Hudon and Brandon Larracuente.
Med is in Season 12, starring Steven Weber, Jessy Schram, Luke Mitchell, Sarah Ramos, Darren Barnet, S. Epatha Merkerson, Oliver Platt and An-Li Bogan.
P.D. is in its 14th season, with Jason Beghe, Patrick John Flueger, Marina Squerciati, LaRoyce Hawkins, Benjamin Levy Aguilar, Arienne Mandi, Naiqui Macabroad and Amy Morton.
All three series are produced by Universal Television, a division of Universal Studio Group, and Wolf Entertainment.
For fans, the appointment is set. Wednesday, January 13, from 7 to 10 p.m. Central on NBC, followed by Peacock on January 14.
