Here’s the official logline for the crossover, via Variety: “When a gas explosion rocks a high-rise, Chicago’s first responders come out in force to rescue hundreds of civilians. It’s the calamity beneath the surface, however, that sends our heroes on a race to save 40 people trapped deep underground, including two of their own.”

The episodes will air on January 29, 2025 starting at 8pm ET with Chicago Fire. The Chicago Med episode follows at 9pm and Chicago P.D. is at 10pm.

“Putting together what is essentially a three-hour action movie is an incredibly ambitious task requiring complete coordination across our writers, casts, crews and producers, along with help from the city of Chicago,” Anastasia Puglisi, executive vice president of Wolf Entertainment and co-executive producer of all three series, told Variety in a statement. “We’re thrilled to have the best talent in every department to meet this challenge, reinforce the #OneChicago brand and provide our fans with a unique and compelling viewing experience.”
