After months of anticipation and swirling rumors, NBC has finally revealed the official fall 2025 premiere dates for its powerhouse Wednesday night lineup — and One Chicago fans couldn’t be more thrilled. The beloved trio — Chicago Med, Chicago Fire, and Chicago P.D. — is locked in for a dramatic return this fall, with new storylines, cast shakeups, and even a few surprises that promise to keep audiences glued to their screens every week.
Mark Your Calendars: The Big Return
NBC has confirmed that Chicago Med Season 11, Chicago Fire Season 14, and Chicago P.D. Season 13 will all premiere on Wednesday, October 1, 2025. The back-to-back time slots remain unchanged, giving fans their familiar three-hour One Chicago block that kicks off with Med, followed by Fire, and closing with the gritty drama of P.D.
The decision to keep all three premieres on the same night signals NBC’s ongoing commitment to the One Chicago universe, which continues to deliver strong ratings and fan engagement even after more than a decade on the air.
What to Expect From Each Show
Chicago Med Season 11
The medical drama will return with major changes at Gaffney Chicago Medical Center. After Season 10 ended with a shocking cliffhanger involving a power outage during a high-risk surgery, viewers are desperate to know whether all patients and staff survived the crisis. Meanwhile, new doctors are set to shake up the ER dynamic. Executive producers have hinted at more storylines involving hospital politics, budget cuts, and a controversial patient ethics case that could divide the staff.
Several returning characters, including Dr. Crockett Marcel and Dr. Charles, will take on more leadership roles, especially in the absence of recently departed cast members. Rumors also suggest a possible crossover with Chicago Fire that could involve a mass casualty event.
Chicago Fire Season 14
The team at Firehouse 51 is bracing for more high-stakes rescues and internal conflict. Season 13 ended with firefighter Blake Gallo contemplating a major life change, and Season 14 will reportedly pick up mere moments after that finale. Fan-favorite Stella Kidd is also rumored to face new leadership challenges, while Severide continues his intense arson investigations — this time with an unexpected twist involving someone from his past.
Additionally, showrunner Andrea Newman teased in a recent interview that “a wedding may be on the horizon,” leaving fans speculating which couple might finally tie the knot. A few new recruits will also join the station, bringing both fresh energy and complications.
Chicago P.D. Season 13
Perhaps the most talked-about of the trio, Chicago P.D. returns in the wake of some major cast shakeups. The departure of Tracy Spiridakos as Hailey Upton in Season 12 sent shockwaves through the fanbase, and Season 13 will explore how Intelligence copes with that loss.
Voight will be tested like never before as he mentors a new team member while battling his own demons. Ruzek and Burgess, still recovering from last season’s trauma, will finally decide whether their on-again, off-again relationship can survive the pressures of their job. Atwater, now in a more senior role, must prove he can lead under Voight’s shadow without compromising his values.
Writers have also promised a more serialized format this season, with one overarching case stretching through multiple episodes, diving deep into corruption, betrayal, and the blurred lines of justice.
Major Cast Changes Across the Franchise
This fall marks a pivotal moment for all three shows, especially with long-standing characters stepping away and new faces stepping in. NBC has confirmed several new additions to each cast, including a former The Night Agent actor joining P.D. as a series regular and a new trauma surgeon entering Med with a mysterious past.
Meanwhile, Chicago Fire will reportedly bid farewell to a recurring character in the first few episodes — an exit that promises to be both emotional and unexpected.
Despite these changes, producers insist the One Chicago core themes of loyalty, family, and resilience remain intact.
Crossovers? Yes, Please.
Although no official crossover has been announced yet, insiders suggest that at least one major three-show event is in the works for late fall 2025. If it happens, it could revolve around a city-wide emergency that calls for every department to join forces. This tradition of epic crossovers is a One Chicago hallmark, and fans eagerly await the announcement.
