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 Schram) 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.
