What to Expect from Chicago Fire Season 15 Episode 4: A Perfect Arson
The FBI asks for Severide’s help with an arson case on Chicago Fire Season 15 Episode 4, “A Perfect Arson.” Though he says it’s “really a job for OFI,” he’s told that the FBI has asked for him specifically.
He won’t be investigating alone, though. It looks like Kidd will be by his side.

This also isn’t a typical arson case. Instead, an arson was staged to cover up the kidnapping of a judge’s daughter. This case could certainly put both Severide and Kidd in danger.
