An arsonist wreaks havoc setting fire to buildings at the stroke of midnight. The Green Hornet and the District Attorney work behind the scenes to aid the Commissioner to put a stop to this hot situation. The commissioner refuses to enlist the aid of a retired top arson investigator because his work previously cost him an eye, but reporter Mike Axford suggests to Britt Reid that the Sentinel can put him to work. Unfortunately, Mike is in for a very big surprise.
