The One Chicago universe is set to make a dramatic return to crossover events with its highly anticipated 2025 special, centered on a catastrophic train accident caused by a gas explosion. This marks the first crossover for Chicago Fire, Chicago Med, and Chicago P.D. since the fan-favorite 2019 event, “Infection.” The three-part episode airs January 29 and promises to reunite the beloved first responders of Chicago in an intense, life-threatening rescue operation.
A High-Stakes Disaster
NBC’s teaser trailer offers a glimpse into the chaos of the crossover event. The disaster begins with a gas explosion that destabilizes a building, leading to a train derailment beneath its foundation. As the trailer reveals, several characters are trapped inside the wreckage, heightening the stakes for everyone involved.
Chief Dom Pascal (Dermot Mulroney) and Lieutenant Stella Kidd (Miranda Rae Mayo) lead the charge in the rescue efforts, battling time as the building threatens to collapse. Tensions escalate when Kidd and Officer Adam Ruzek (Patrick John Flueger) find themselves trapped aboard the damaged train. Meanwhile, Lieutenant Kelly Severide (Taylor Kinney) is visibly shaken as he fears for Kidd’s safety, amplifying the emotional intensity of the mission.
