The NBC drama franchise known as One Chicago is returning for the 2026 fall television season, with TV Insider reporting that Chicago Med, Chicago Fire, and Chicago P.D. will all debut new seasons on Wednesday, October 7.
Chicago Fire Season 15 Premiere and Character Fates
According to TV Insider, Chicago Fire left off with the most severe cliffhanger of the franchise, trapping almost all of Firehouse 51 inside a burning building or on an exterior ladder. Miranda Rae Mayo highlights the season’s peril in the new promotional trailer by stating, “When it feels like life or death, it can be easy to justify stepping over other people to save yourself… But you live or die together.” While the promotional video does not reveal the survival status of characters caught in the fire, production updates confirm that Dermot Mulroney, who plays Dom Pascal, and Joe Miñoso, who plays Joe Cruz, will exit the show following the premiere and a handful of subsequent episodes, respectively.
Chicago Med Season 12 Personnel Conflicts
On Chicago Med, S. Epatha Merkerson’s character Sharon Goodwin faces a battle to save her job after taking accusations of leaking personnel information, according to TV Insider. The upcoming twelfth season also addresses the romantic and professional fallout between Dr. Hannah Asher, played by Jessy Schram, and Dr. Dean Archer, played by Steven Weber, following a storyline where the characters had a baby, Archer confessed his romantic feelings, and Asher kissed him.
Chicago P.D. Season 14 Storylines and Schedule
Over on Chicago P.D., Sergeant Hank Voight, played by Jason Beghe, confronts a complex moral dilemma involving Eva Imani, played by Arienne Mandi, according to TV Insider. Voight must determine how to handle the revelation that Imani’s sister, Shari, played by Selin Çuhadaroglu—who was kidnapped and groomed as a young girl—is guilty of murder. The teaser trailer also offers a brief glimpse of action sequences involving the Intelligence unit.
