No New One Chicago Tonight

The Fall TV season is officially underway, with big premieres like The Voice, Brilliant Minds, Doc, and Murder in a Small Town already hitting NBC and beyond. But One Chicago fans will need to hold their breath just a little longer—because Chicago Fire, Chicago Med, and Chicago P.D. aren’t airing new episodes on September 24.

When Does One Chicago Return?

Circle the date: Wednesday, October 1, 2025. That’s when NBC’s powerhouse lineup roars back with three back-to-back premieres:

• Chicago Med Season 11 at 8/7c

• Chicago Fire Season 14 at 9/8c

• Chicago P.D. Season 13 at 10/9c

Episodes will stream the following day, October 2, on Peacock.

What to Expect in the Premieres

• Chicago Med: The doctors face an intense opener as they treat a family burned in a devastating house fire. Dr. Lenox is also tasked with saving two sisters injured during a rave turned tragedy, while the fallout of Hannah Asher’s pregnancy continues to stir tension inside the ER. Meanwhile, Goodwin clashes with a staff member over looming staffing changes.

• Chicago Fire: Firehouse 51 adjusts to its newest recruit—a bold arrival who immediately ruffles feathers. As chaos sweeps through Chicago, the team faces high-stakes rescues. Veteran firefighter Herrmann grapples with the personal consequences of stepping down as lieutenant, adding emotional depth to the season’s fiery start.

• Chicago P.D.: After Intelligence was disbanded in the Season 12 finale, Voight is forced into an uneasy alliance to hunt down a killer. But while he fights for justice, he also faces the daunting task of bringing his fractured team back together.

The Bottom Line

There may be no One Chicago tonight, but the wait is almost over. On October 1, NBC delivers three hours of nonstop drama—a night packed with medical crises, blazing rescues, and criminal investigations that will set the tone for the entire season.
