One Chicago's Massive Crossover Brings Together 'Fire,' 'Med,' and 'P.D.' Teams to the Streets in New Images

On Wednesday, January 29, all essential workers from the One Chicago franchise will leave their regular places of work and go to the streets when tragedy strikes. For the first time in five years, Chicago Fire, Chicago Med, and Chicago P.D. will stage a one-night crossover event as teams from all three shows join forces to do what they do best following an explosion that leaves hundreds of casualties. "When a gas explosion rocks a high-rise, Chicago’s first responders come out in force to rescue hundreds of civilians. The calamity beneath the surface, however, sends our heroes on a race to save 40 people trapped deep underground, including two of their own," reads the official crossover description.
