Two former members of the Intelligence Unit on 'Chicago P.D.', Jesse Lee Soffer and Tracy Spiridakos, are reprising their roles as Jay Halstead and Hailey Upton for an upcoming three-show crossover event on NBC. The crossover begins with Firehouse 51 being called to an airfield after a plane goes silent mid-air, leading to a bigger mystery with consequences that could put countless lives in jeopardy. Halstead left the Chicago P.D. for a job tracking drug cartels, while Upton is now an FBI agent, but they will join their former P.D. allies to investigate the case.

Why it matters

The return of Halstead and Upton, known as 'Upsteadgess' by fans, is highly anticipated, as the two characters had a popular romantic storyline on 'Chicago P.D.' Soffer exited the show in Season 10, while Spiridakos was last seen in Season 11, so their reunion for this crossover event is sure to excite viewers.

The details

In the crossover event, Halstead has been deep undercover, which leads him on a path to the same case that Upton is investigating out of her Detroit field office as an FBI agent. The two former Chicago P.D. allies will join forces to solve the mystery, which has 'consequences that could ripple far beyond the runway and put countless lives in jeopardy.'

  • The crossover event will air on March 4, 2026, after the shows return from the Winter Olympics break.
  • Soffer exited 'Chicago P.D.' in Season 10, and Spiridakos was last seen in Season 11.
