When Tony Caruso is hired to go undercover for the U. S. Fish and Wildlife Service, he has no idea that his life will change forever. He is tasked to track down an Asian ring of smugglers who are killing black bears, elk, and deer. Eventually, he ends up in the southern Cascades in the mushroom fields, where he must fight not only the Asian game smugglers, but Asian gangs from San Francisco and Seattle. As Tony tightens the noose around the smugglers, the case becomes personal. Now he must encounter these brutal killers in the remote forest, where his survival depends on his own military training and his favorite sidekick, Panzer, his giant schnauzer and former German military working dog.
