Miranda Rae Mayo (Stella Kidd) continues to shine as a fan favorite, bringing grit and heart to the firehouse drama.
Chicago Med
Now entering its milestone tenth season, Chicago Med is once again placing its ensemble of doctors and nurses in the spotlight. S. Epatha Merkerson (Sharon Goodwin) anchors the hospital as its respected administrator, while Oliver Platt (Dr. Daniel Charles) continues to deliver nuanced portrayals of psychiatry’s challenges. Dominic Rains returns as Dr. Crockett Marcel, a character who has steadily grown into a leading man within the series.

Chicago P.D. has consistently delivered hard-hitting storylines, and its thirteenth season promises no shortage of intensity. Jason Beghe returns as Hank Voight, the stoic leader of the Intelligence Unit, whose methods and morals continue to be tested. LaRoyce Hawkins (Kevin Atwater) has become a fan-favorite for his blend of empathy and toughness, while Marina Squerciati (Kim Burgess) and Patrick John Flueger (Adam Ruzek) carry on one of the show’s most compelling relationships, with their professional and personal lives deeply intertwined. Tracy Spiridakos, who plays Hailey Upton, remains a central figure, though her character’s arc is rumored to be facing pivotal changes.
Why the One Chicago Franchise Endures
Together, the three series create a unique television ecosystem, with crossover episodes offering fans an interconnected experience. The franchise has thrived not only because of its pulse-pounding emergencies and action but also because of its emphasis on character-driven storytelling. Viewers have watched these characters grow, struggle, and triumph over more than a decade, making premiere night feel like a reunion with old friends.
As October 1 approaches, anticipation is running high. With returning favorites, shifting dynamics, and the promise of new challenges, One Chicago remains one of NBC’s most enduring and beloved franchises. Whether at the firehouse, the hospital, or the precinct, the city of Chicago is in capable hands once again.
