NBC has officially confirmed the return dates for the much-loved One Chicago franchise, consisting of Chicago Fire, Chicago P.D., and Chicago Med. Fans will need to mark their calendars for Wednesday, October 1, 2025, as all three shows will be airing new episodes in a back-to-back block, with Chicago Med at 8 p.m., followed by Chicago Fire at 9 p.m., and wrapping up with Chicago P.D. at 10 p.m..

While the premiere dates are later than expected, this coordinated launch will help maintain the excitement and energy that fans have come to expect from these interconnected dramas. Even though some viewers were hoping for a return in September, NBC’s decision to roll out the shows in October ensures they keep the momentum going, without breaking the rhythm that the series have established. The unified return guarantees that each show will continue its storytelling arc in sync, and there’s plenty to look forward to for fans of all three.

What to Expect from Each Show in the One Chicago Lineup:

• Chicago Med: The medical drama will delve deeper into the ongoing struggles of the staff at Gaffney Chicago Medical Center. Chicago Med fans can expect a continued focus on Hannah’s pregnancy and her complicated relationship dynamics. Additionally, Dr. Charles’ personal life will be explored further, as well as the potential for new characters like Dr. Mitch Frost and Dr. Ivy Lenox to gain more prominence in upcoming episodes.

• Chicago Fire: Chicago Fire will be undergoing some shifts in personnel, with some important characters leaving the team. While Taylor Kinney’s Kelly Severide will continue to lead Firehouse 51, fans will have to adjust to the absence of Daniel Kyri’s character, Darren Ritter, and Jake Lockett’s character, Sam Carver. It’s unclear who will step in to fill those roles, but viewers can expect big changes as the firehouse faces new challenges.

• Chicago P.D.: Hank Voight (Jason Beghe) will still be at the heart of Chicago P.D., and fans can expect to see more of up-and-coming characters like officer Kiana Cook. While there will likely be some focus on Voight’s personal life, the series will continue its signature mix of high-stakes cases and intense investigations.

The Importance of a Coordinated Return

Although fans may have hoped for an earlier start, NBC’s strategic decision to release all three shows on the same night in October underscores their commitment to the interwoven storylines that have made One Chicago so successful. The series are known for occasional crossovers and for the seamless narrative threads that tie them together, and this shared premiere date allows the stories to unfold across all three shows in real-time. Fans can expect to see developments in Chicago Fire that could spill over into Chicago P.D. and Chicago Med, keeping the drama and intrigue high across the night.

With so many changes on the horizon, including personnel shifts and unresolved cliffhangers, One Chicago’s fall premiere is set to deliver an action-packed season filled with suspense, drama, and deep character development. The return of all three shows will be a must-watch for long-time fans and newcomers alike.

What’s Next?

As we approach the fall premiere, fans can begin speculating on how these changes will impact the team dynamics. Will Chicago Fire’s new team members mesh with the established crew? How will the emotional turmoil on Chicago Med affect the hospital staff’s ability to provide care? And will Chicago P.D. continue to walk the tightrope between personal conflict and professional duty? There’s a lot to look forward to in the One Chicago universe this season, and the wait for October 1, 2025, will surely be worth it.
