It's time for the fireman's fair in a small Idaho town. Everything was great... until two people became victims of spontaneous human combustion... Or, did they?

After seeing the news story of the two victims, Johann, Robert, and Theresa high tail it to Idaho to investigate the incident. They find that these weren't the first two people in this small town to spontaneously combust, and the evidence points to a vengeful spirit.

When they have the final face-off with the vengeful spirit, the team seems to be at a loss until they receive some powerful help from an equally powerful source.
