NBC is about to set the One Chicago universe on fire. Chicago Fire, Chicago Med, and Chicago P.D. are officially coming together for high-stakes crossover episodes this March, promising an explosive event fans have been waiting for.
Details are being kept tightly under wraps, but the network is teasing a storyline so intense it will force all three teams into the same crisis — blurring the lines between firehouse heroics, hospital chaos, and police action. Lives will be on the line, secrets will surface, and no character will walk away unchanged.
Crossover events have long been some of the franchise’s most unforgettable moments, and this one is already shaping up to raise the stakes even higher. With fan-favorite characters colliding across shows, March is set to deliver nonstop tension, emotional fallout, and must-see television.
For One Chicago fans, this isn’t just another crossover — it’s an event that could change everything.
