In a thrilling announcement that’s set the One Chicago fanbase buzzing, beloved Chicago P.D. stars Jesse Lee Soffer and Tracy Spiridakos are officially returning to their iconic roles in the franchise’s upcoming One Chicago crossover event airing March 4, 2026 on NBC.
After years away from the Chicago P.D. beat — Soffer exited the series in 2022 after ten seasons as Detective Jay Halstead, and Spiridakos left in 2024 following a memorable seven-year run as Detective Hailey Upton — the duo is back in action for a high-stakes, three-hour event that will span Chicago Fire, Chicago Med, and Chicago P.D..
The crossover kicks off in dramatic fashion when Firehouse 51 is dispatched to a mysterious emergency involving a passenger jet that suddenly goes silent mid-air. What begins as a rescue quickly expands into a dangerous case that draws all departments into a tense, interconnected investigation.
Fans of the on-screen couple — affectionately nicknamed “Upstead” — have long clamored for closure after their emotional on-show marriage and subsequent separation. Though Halstead left town for an Army mission in Bolivia and Upton pursued a new path, both characters are now drawn back into the Windy City under surprising circumstances: Upton returns as an FBI Special Agent from Detroit, while Halstead emerges from undercover work tied to the same federal case.
Their return marks their first on-screen appearances in the One Chicago universe since exiting the franchise, igniting huge excitement across social media and online forums alike. With the crossover serving as one of the biggest One Chicago events of the season, longtime viewers are eager to see whether the duo can finally get the story arc fans have been waiting for.
Whether this reunion leads to romance, redemption, or just riveting drama, one thing is certain: the Windy City just got a whole lot more intense.
