One Chicago Three-Series Crossover Set To Air On NBC In January 2025

The first responders in the One Chicago universe just got a little more connected. This coming January, NBC is set to air a three-series crossover event, bringing all your favorite characters from Chicago Fire, Chicago Med, and Chicago P.D. together in three exciting episodes.

In the first One Chicago crossover since 2019, fans can expect plenty of action. When a gas explosion rocks a high-rise, Chicago’s first responders come out in force to rescue hundreds of civilians. But it’s the calamity beneath the surface that sends our heroes on a race to save 40 people trapped deep underground—including two of their own. 

“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,” said Anastasia Puglisi, Wolf Entertainment Executive Vice President and co-executive producer of the One Chicago series. “We’re thrilled to have the best talent in every department to meet this challenge, reinforce the One Chicago brand, and provide our fans with a unique and compelling viewing experience.”

Catch all three crossover episodes on Wednesday, January 29th on NBC from 8-11p.m. ET/PT. Chicago Fire will kick things off at 8 p.m., followed by Chicago Med at 9 p.m. and concluding with Chicago P.D. at 10 p.m. Stream the crossover episodes the next day and catch up on past episodes on Peacock.
