NBC’s One Chicago Universe Expands This Fall But With a Twist No One Saw Coming

The sirens are wailing and hearts are racing — NBC’s One Chicago universe is officially expanding this fall, but not in the way anyone expected.

After years of thrilling crossovers between Chicago Fire, Chicago P.D., and Chicago Med, NBC is now preparing to shake things up with a brand-new twist: a limited series set outside of Chicago — but still deeply connected to its core characters. That’s right. According to network insiders, the new show will take viewers into uncharted territory with a former fan-favorite character at the center of the drama.

Sources say the new spin-off, rumored to be titled Chicago: Division One, will follow an elite federal task force led by none other than a surprise return from a previously written-off character — and fans are already buzzing about who it could be. Could it be Antonio Dawson? Erin Lindsay? Or someone else we never saw coming?

Even more shocking, the new series won’t premiere in the traditional fall lineup slot. Instead, it’s being teased as a "special event season" — a shorter, high-stakes arc meant to test the waters for a potential fourth pillar in the One Chicago world.

Online, fan reactions are pouring in:

“Please be Erin Lindsay! We need her back!”
“A federal task force? Now that’s a twist!”
“They better not mess with my Chicago Fire schedule ”

One thing’s for sure — NBC isn’t done playing with our emotions just yet. Get ready, Chi-hards: this fall, the Windy City won’t be the only place where the action goes down.
