See how it all goes down when Chicago Fire airs Wednesday at 9/8c on NBC.
Plus, Brett (Kara Killmer) and Foster (Annie Ilonzeh) respond to a call where a Halloween prank turns deadly serious.
Keeping with that annual tradition, Wednesday’s Chicago Fire will see Truck 81 take on a seemingly normal call but things quickly escalate when they realize the situation is far worse than they anticipated.
But for the firefighters of Firehouse 51, it’s one of the most nightmarish times of the year, as foolish pranks go wrong and turn into unpredictable emergencies.
