Season 13 of Chicago P.D. has been anything but calm. The Intelligence Unit has been pushed to its limits, with cases growing darker, stakes getting higher, and Voight’s team constantly forced to make impossible choices in the name of justice.

Every episode feels like it’s building toward something bigger, something that could shake up the unit in ways no one sees coming.

And just when it seems like the squad has finally found its footing again, a major case begins unfolding across the entire One Chicago universe, setting the stage for an event that could bring old ties, unresolved history, and familiar faces back into the chaos.

NBC has confirmed that Jesse Lee Soffer and Tracy Spiridakos will reprise their Chicago P.D. roles as Jay Halstead and Hailey Upton in an upcoming One Chicago crossover event. The news broke on February 4, 2026, immediately sparking excitement among longtime franchise fans.

The announcement is especially significant because this marks the first time both actors will appear on-screen in the One Chicago universe since their exits. Soffer departed the series after Season 10 in 2022, while Spiridakos left after Season 11 in 2024.

Naturally, the update has reignited buzz around “Upstead,” the fan-favorite pairing that became one of Chicago P.D.’s most talked-about relationships.

So what major case is big enough to bring them back?

The One Chicago crossover will air on March 4, 2026, running from 8 p.m. to 11 p.m. ET/PT on NBC. The event will unfold across three episodes, beginning with Chicago Fire, continuing with Chicago Med, and concluding with Chicago P.D.

The story kicks off when Firehouse 51 responds to a chilling emergency involving a passenger jet that goes silent mid-flight and lands at an airfield under suspicious circumstances. What starts as a rescue operation soon expands into a much larger mystery, pulling in multiple departments across Chicago.

As the investigation intensifies, Intelligence becomes involved, creating the perfect opportunity for Jay and Hailey’s paths to cross again, this time under extremely dangerous circumstances.

Jesse Lee Soffer and Tracy Spiridakos returning to Chicago P.D. for the March 2026 One Chicago crossover is shaping up to be the equivalent of one of Marvel's biggest moments in years for Chicago P.D. fans. And for those who have missed seeing Jay Halstead and Hailey Upton together, March 4 cannot come soon enough.
