March is about to bring total chaos to the One Chicago universe. Chicago Fire, Chicago Med, and Chicago P.D. are colliding in an explosive three-show crossover event that promises citywide devastation, impossible choices, and consequences that won’t stay contained within a single series.
A single crisis will ripple across the firehouse, the emergency room, and the streets — forcing familiar faces into unfamiliar roles as the lines between rescuer, doctor, and detective blur. As the danger escalates, alliances will be tested, secrets exposed, and lives pushed to the brink.
NBC’s crossover events are known for delivering some of the franchise’s most unforgettable moments, and this one is shaping up to be no exception. With every hour raising the stakes, One Chicago fans won’t want to miss a second of the madness.
When March hits, everything collides — and nothing will be the same.
