Fans of Chicago Med, Chicago Fire, and Chicago P.D. have something big to look forward to in 2025. After years without a full-scale crossover, NBC is bringing back the One Chicago tradition with an epic three-part event set to air in January 2025. Here’s everything we know about the highly anticipated reunion of Chicago’s finest first responders.
A Look Back at One Chicago Crossovers
The One Chicago franchise, executive produced by Dick Wolf, has long been a staple of NBC’s lineup. While each series—Chicago Fire, Chicago Med, and Chicago P.D.—focuses on different aspects of public service, they share a common setting and have frequently featured character crossovers.
The tradition of full-scale crossover events began in 2016 with a three-part storyline spanning Fire’s “The Beating Heart,” Med’s “Malignant,” and P.D.’s “Now I’m God.” These events quickly became a fan-favorite annual tradition, with major crossovers taking place in 2017, 2018, and 2019. Some crossovers even expanded to include characters from Law & Order series, further connecting the Wolf Entertainment universe.
However, it’s been over five years since the last full One Chicago crossover, making the return of this high-stakes event even more exciting.
What to Expect in 2025
The 2025 One Chicago crossover is set to air on Wednesday, January 29, 2025. The event will kick off with Chicago Fire, followed by Chicago Med, and conclude with Chicago P.D. in a seamless, action-packed three-hour marathon.
NBC has teased that the storyline will center on a devastating explosion that rocks the city, forcing first responders from all three teams to work together. While specific plot details remain under wraps, fans can expect to see characters from each show interact in new and exciting ways.
The One Chicago Instagram account has already teased behind-the-scenes footage, showing cast members from the different series taking selfies and preparing for the ambitious production. In a caption celebrating the crossover, the post declared, “We’re in our crossover era,” sparking excitement among fans.
One particularly enthusiastic fan summed up the excitement in the comments: “Crossovers are back, baby!”
Why Fans Love One Chicago Crossovers
Part of the magic of One Chicago crossovers is watching how the characters’ lives intersect in ways that are both thrilling and emotionally resonant. Whether it’s firefighters from Firehouse 51 rushing victims to Gaffney Chicago Medical Center or detectives from the Intelligence Unit working with medics to solve a case, these events showcase the interconnected nature of Chicago’s first responders.
Additionally, crossovers provide an opportunity for fans of one show to explore the others, often creating new viewers for the entire franchise.
