After five long years, the One Chicago universe is gearing up for a thrilling crossover event set to air in early 2025. Combining the forces of Chicago Fire, Chicago Med, and Chicago P.D., this crossover promises to be an edge-of-your-seat experience that fans won’t want to miss. NBC has teased that the upcoming event will essentially play out like a “three-hour action movie,” with plenty of drama, danger, and emotional stakes for beloved characters.
Here’s everything we know about the highly anticipated crossover, including the air date, storyline, and how each show will play a pivotal role.
What’s the Story Behind the Crossover?
NBC recently confirmed that the One Chicago crossover will center on a catastrophic event ripped straight from a disaster movie. According to the official synopsis, a gas explosion in a high-rise building plunges Chicago into chaos, forcing first responders from Firehouse 51, Gaffney Chicago Medical Center, and the Intelligence Unit to join forces.
The disaster escalates when 40 civilians—along with two key members of the team—become trapped deep underground. The press release hints that this subplot will form the emotional core of the crossover, though the identities of the trapped characters remain a mystery.
Producer Anastasia Puglisi described the ambitious event in a statement:
“Putting together what is essentially a three-hour action movie is an incredibly ambitious task requiring complete coordination across our writers, casts, crews, and producers, along with help from the city of Chicago. We’re thrilled to have the best talent in every department to meet this challenge.”
The crossover will also explore the ripple effects of the disaster on each show’s respective team. From Chicago’s firefighters risking everything to save lives, to the medical staff dealing with an influx of casualties, to the police uncovering deeper threats tied to the explosion, every minute promises high-stakes drama.
Where Did We Leave Off?
Heading into the crossover, each One Chicago show left viewers with unresolved storylines that are set to collide during this event.
- Chicago Fire: Firehouse 51 is in turmoil as the new Fire Department Chief, Dom Pascal (Dermot Mulroney), struggles with balancing his job and personal life. Meanwhile, Joe Cruz (Joe Minoso) faces a chilling threat when a gang from his past resurfaces, vowing revenge. Veteran firefighters Mouch (Christian Stolte) and Herrmann (David Eigenberg) anxiously await the results of their promotional exams.
- Chicago Med: At Gaffney Chicago Medical Center, Director Sharon Goodwin (S. Epatha Merkerson) is held hostage by her stalker, Cassidy, in a heart-stopping cliffhanger. As Dr. Dean Archer (Steven Weber) witnesses the standoff, viewers are left wondering how—or if—Goodwin will escape unscathed.
- Chicago P.D.: Officer Dante Torres (Benjamin Levy Aguilar) grapples with the emotional aftermath of losing his lover and former informant, Gloria Perez, in a shootout. To make matters worse, their affair has been exposed, placing Torres in hot water with his colleagues and Chief Charlie Reid (Shawn Hatosy).
The crossover will weave these plotlines into the larger narrative of the high-rise explosion, promising to resolve lingering questions while introducing new challenges.
