When forest fire forensics expert Porter Cassel is called in to help catch a serial arsonist who goes by the name "Lorax", he must juggle his official investigation with a personal one: the Lorax's modus operandi resembles that of a long-dormant ecoterrorist who planted the bomb that killed Cassel's fiance;. His personal investigation creates friction with the Mounties, who have jurisdiction over the latest series murders. As the search continues, Cassel finds he has more to worry about than just a turf battler, when he is framed for the murder of one of the suspects in the case. How will he prove his innocence, as well as discover the identity of the arsonist?
