The action will be firing off on all cylinders asChicago Med, Chicago Fire, and Chicago P.D. join forces.
This is not a drill, Chihards! A three-part One Chicago crossover event is coming as the tenacious Windy City heroes of Chicago Med, Chicago Fire, and Chicago P.D. team up to face whatever crisis comes their way.
Who doesn’t love a One Chicago crossover? The 2025 event was an action-packed “Marvel”-level crossover as the Gaffney doctors, Firehouse 51 first responders, and tenacious Intelligence Unit teamed up on a city-wide bombing that had many One Chicago fan favorites feeling the heat. Now for the 2026 crossover, we’ve got a few swoon-worthy One Chicago love stories to see play out in a bona fide three-parter with all units working the same emergency.
When does the One Chicago crossover event premiere?
The three-hour One Chicago crossover will air on Wednesday, March 4, beginning at 8/7c. However, unlike typical One Chicago Wednesday lineups, fans will start the night with a Firehouse 51 rescue that is bound to bring in the rest of the Windy City heroes.
Chicago Fire will lead the cavalry of One Chicago crossover episodes at 8/7c, followed by Chicago Med at 9/8c, and Chicago P.D. at 10/9c on NBC during the typical One Chicago Wednesday block.
Where to stream the One Chicago crossover event
If you miss the TV broadcast, fret not; Chihards can stream the crossover episodes the next day on Peacock, making sure to view them in the correct order of Fire Season 14, Med Season 11, and P.D. Season 13.
What is the 2026 One Chicago crossover about?
The official logline for the three-part One Chicago episode promises: “Firehouse 51 is called to an airfield when a passenger jet suddenly goes silent mid-air, triggering a high-stakes emergency. Their discovery cracks open a bigger and deadlier mystery — one with consequences that could ripple far beyond the runway and put countless lives in jeopardy.”
Chicago Fire producer Reza Tabrizi spoke to NBC Insider about the writing process behind bringing these blood-pumping crossover episodes to life, which requires a synergy built upon years of One Chicago world-building.
“We really like when we can have characters have storylines across the shows… The [One Chicago] writers’ rooms are close to each other, and there are conversations going on all the time,” Tabrizi shared. “As far as what’s happening with the characters and how we can engage the characters from other shows in each show. That’s been ongoing since the beginning… I think it’s kept the writers’ rooms close. Even if the show runners have changed, the writers’ rooms’ communications have, if anything, gotten closer over the years.”
What to know ahead of the One Chicago crossover event
Tensions have been high on Season 14 of Chicago Fire as overhauls at City Hall jeopardize the happy harmony of Firehouse 51, leading to some shocking relocations. Meanwhile, Kelly Severide (Taylor Kinney) and Stella Kidd (Miranda Rae Mayo) have been going through it after becoming foster parents and being forced to say goodbye to their son way earlier than anyone expected.
Chicago Med Season 11 has been an emotional rollercoaster as Gaffney fan favorites Dr. Hannah Asher (Jessy Sch
ram) and Dr. Dean Archer (Steven Weber) prepare for a baby and a co-parenting journey. The romance doesn’t end there, either; Dr. Caitlin Lenox (Sarah Ramos) and Dr. Mitch Ripley (Luke Mitchell) are warming up to each other after surviving a near-death experience together, leading to a shocking hook-up that made our hearts race.
Last but certainly not least, there has been no shortage of twists and turns on Season 13 of Chicago P.D. as Sgt. Hank Voight (Jason Beghe) navigates a grueling blackmail scheme from a higher-up in the CPD. Meanwhile, his newest recruit, Officer Eva Imani (Arienne Mandi), is fitting right in at the Intelligence Unit as she tackles each case with infallible zeal.
While waiting for the One Chicago crossover event, make sure to stay caught up with Season 14 of Chicago Fire, Season 11 of Chicago Med, and Season 13 of Chicago P.D. by watching One Chicago Wednesdays on NBC, or by steaming episodes on Peacock.
