Two of Firehouse 51's own went missing in the final moments of Chicago Fire 's fall finale, but that doesn't mean the rest of the team will get to take a breather from their day jobs to look for Mills and Brett.
In this exclusive sneak peek from Tuesday's new episode (10/9c, NBC), the rest of the squad doesn't get called to just any fire - they get must report to the scene of a fire at a storage unit facility. "Storage units are the pits," Herrmann ( David Eigenberg ) tells Dawson (Monica Raymund ). "You got to bust into each unit and worse, you got no idea what you're going to find behind each door."
Sure enough, what Severide ( Taylor Kinney ) finds behind one of the doors knocks him out. Check out the exclusive sneak peek below to see the mysterious cause.
Chicago Fire airs Tuesdays at 10/9c on NBC.
