In the three-parter, “a gas explosion rocks a high-rise,” and “Chicago’s first responders come out in force to rescue hundreds of civilians,” reads the official synopsis. “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.”

With filming underway on the big crossover, TVLine has gathered behind-the-scenes photos from the shows’ cast members, as shared on social media.
