If you’re anything like the millions of loyal One Chicago fans around the world, you’ve been anxiously awaiting news of when Chicago Med, Chicago Fire, and Chicago P.D. will return from their mid-season break. These three interconnected dramas have become a midweek staple for NBC viewers, delivering high-octane action, heartwarming personal stories, and powerful ensemble performances week after week. But as the calendar ticks past the halfway point of the year, fans are wondering: When are the shows coming back?
Mark your calendars: All three One Chicago shows—Chicago Med, Chicago Fire, and Chicago P.D.—will return on Wednesday, September 17, 2025. As always, the shows will air back-to-back in their usual primetime block on NBC, starting with Chicago Med at 8 p.m. ET, followed by Chicago Fire at 9 p.m., and Chicago P.D. wrapping up the night at 10 p.m. Mid-season breaks are nothing new in network television. These hiatuses allow production teams time to complete the back half of the season and help networks strategically spread episodes across the full broadcast year. For One Chicago, the break was slightly longer than usual in 2025 due to a reshuffling of NBC’s spring schedule, which accommodated live events and the early debut of new series.
Chicago Med left fans reeling with emotional cliffhangers and personal dilemmas. As the doctors and nurses of Gaffney Chicago Medical Center return, expect high-stakes cases that mirror current medical debates and ethical dilemmas. Dr. Charles (Oliver Platt) will continue to navigate the hospital’s mental health challenges while mentoring a new generation of residents. Meanwhile, Maggie’s future at the hospital hangs in the balance following a critical administrative shake-up. There are whispers of a surprise romance blossoming between two unlikely characters—and it’s sure to spark conversation.
After a nail-biting mid-season finale involving a high-rise blaze that nearly claimed the lives of two squad members, Chicago Fire returns with a focus on healing, leadership transitions, and station house tensions. Kelly Severide (Taylor Kinney) steps into a new role that may permanently shift the team dynamic, while Stella Kidd faces a moral crossroads that challenges her core values as a firefighter and a leader.
Arguably the darkest and most intense of the three shows, Chicago P.D. returns with the Intelligence Unit more fractured than ever. Voight (Jason Beghe) is grappling with the fallout from a failed undercover operation, and with Upton (Tracy Spiridakos) set to exit later this season, her final episodes promise to be both emotionally charged and action-packed. Newer team members will step up, and a season-long criminal case introduced in the first half is set to resurface in a shocking way. With internal affairs sniffing around and past sins threatening to resurface, the second half of Season 12 may be one of the most gripping yet.
Every One Chicago fan loves a good crossover, and while nothing has been officially announced, insiders suggest that at least one mini-crossover event is being planned for early November. This event may tie a medical case into a criminal investigation, bringing Med and P.D. into direct collaboration, with Fire caught in the middle. These kinds of events are not only fan favorites but also help deepen the interconnected universe, allowing characters to grow beyond the walls of their respective shows.
