Tonight’s Chicago Fire episode is going to be explosive – in more ways than one.

“I Am the Apocalypse” will see the Chicago Fire team working to help scores of people who have fallen victim to a deadly gas leak.

However things are escalated when a fake patient planted inside the hospital goes on a suicide mission armed with a grenade and claiming to be the carrier of a deadly airborne disease.

Trying to stop the madman from engaging the explosive device, a member of the firehouse team is severely wounded in the blast and left to face life-threatening injuries.

With no other choice, Chicago Med is forced into lockdown until doctors and the Hazmat team can determine the severity of the airborne virus.

We’ve got 4 brand new sneak peek clips from tonight’s over the top episode to share below.

“I Am the Apocalypse” airs Tuesday April 7 on NBC.
