The Season 12 finale of Chicago Fire will be a scorcher. 

How to Watch

Watch Chicago Fire Wednesdays at 9/8c on NBC and next day on Peacock.

Throughout Season 12, viewers have been taken on an emotional journey as Firehouse 51 acclimates to its new company. After losing Blake Gallo (Alberto Rosende) and Sylvie Brett (Kara Killmer), it's been a change of pace for everyone. Amid these staff changes, we have some unresolved tension.  Leadership shifts in the CFD have threatened 51's livelihood and complicated  Wallace Boden's (Eamonn Walker) position. Meanwhile, suspicious new candidates have made their way to 51 with unclear motives. Plus, Violet Mikami (Hanako Greensmith) and Sam Carver (Jake Lockettstill haven't taken their "casual" relationship to the next level.

In NBC Insider's chat with Chicago Fire showrunner Andrea Newman ahead of the finale, she revealed Boden will have a big choice to make.

"Boden is always looking out for the best ways to lead Firehouse 51, and in the finale, he will come to a surprising decision about how to do that, and who to do it with. In the meantime, he’s got adversaries to battle and will be part of a shocking call that will make him question leadership in all its forms."

In a March 2024 NBC Insider interview with Hanako Greensmith, she teased three words to describe Season 12: "Bittersweet, emotional, and supportive."

“I really feel like this season, with people leaving, there's been this kind of wonderful passing of the baton…" Greensmith continued. "I think there's a lot of elements of people leaving and allowing space for others to step forward, and yeah, I think that’s beautiful.”
