NBC's 'One Chicago' Returns With First Crossover Event in Five Years

The three-hour special unites 'Chicago Fire,' 'Chicago Med,' and 'Chicago P.D.' for a high-stakes rescue mission following a catastrophic gas explosion.

The crossover event marks the first collaboration of NBC's 'One Chicago' franchise since 2019, spanning three episodes across 'Chicago Fire,' 'Chicago Med,' and 'Chicago P.D.'
The storyline centers on a gas explosion in a high-rise building, with first responders racing to save 40 people trapped underground, including two of their own team members.
Showrunners from all three series worked closely to develop the interconnected plot, which was described as the most ambitious crossover in the franchise's history.
The event airs on January 29 from 8 to 11 p.m. ET/PT on NBC and will be available for streaming on Peacock starting January 30.
Producers highlighted the cinematic quality and emotional depth of the episodes, which feature key moments for characters like Kelly Severide, Stella Kidd, and Adam Ruzek.
