NBC has officially locked in the highly anticipated return of its powerhouse One Chicago lineup, with Chicago P.D., Chicago Fire, and Chicago Med all set to premiere new seasons on October 1, 2025. The news has ignited excitement among fans who eagerly await the next chapter in Dick Wolf’s long-running franchise.
Among the lineup, Chicago P.D. Season 13 is already generating the most buzz, particularly following the seismic events of its twelfth season. The series, known for blending gripping crime cases with deeply personal character arcs, will now explore the consequences of last season’s dramatic exits and reunions. With the addition of Arienne Mandi as Eva Imani, a new series regular, the Intelligence Unit will be forced to adapt to fresh dynamics while still reeling from past traumas.
NBC’s strategy to keep One Chicago anchored on Wednesday nights underscores the enduring popularity of the franchise. For years, Chicago Fire, Chicago Med, and Chicago P.D. have dominated primetime ratings, offering fans a seamless night of interconnected storytelling. This season, the network is doubling down on the formula, ensuring audiences get their fix of fast-paced medical emergencies, blazing infernos, and high-stakes police investigations all in one night.
While the network is keeping most plot details tightly under wraps, Chicago P.D. showrunner Gwen Sigan has teased that the upcoming season will push the Intelligence Unit into uncharted territory. The emotional fallout of Officer Adam Ruzek’s near-death experience, Detective Kim Burgess’ ongoing struggles with trauma, and Torres’ shifting loyalty are expected to take center stage. The introduction of Mandi’s character Eva Imani — a tough, enigmatic former military contractor — promises to disrupt the status quo and challenge the authority of Sergeant Hank Voight.
Meanwhile, Chicago Fire will continue to explore the leadership transition at Firehouse 51, and Chicago Med will address lingering questions surrounding its latest staffing shakeups. Together, the three series form the backbone of NBC’s fall primetime slate, showcasing the network’s confidence in the staying power of Wolf Entertainment’s franchise.
For fans, the October 1 premiere date provides a clear marker on the calendar. With cliffhangers still fresh in their minds, viewers are eager to see how the storylines unfold across the interconnected series. Social media buzz has already ramped up, with loyal fans speculating about crossovers, reunions, and whether Season 13 of Chicago P.D. could mark the beginning of a new era for the Intelligence Unit.
As production continues in Chicago, NBC is expected to release first-look trailers in the coming weeks, further stoking anticipation. But one thing is certain: the return of One Chicago promises another season filled with emotional drama, shocking twists, and unforgettable storytelling.
