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 in the remote mountains of Oregon. He is tasked to track down an Asian ring of smugglers who are killing black bears for gallbladders and shooting elk and deer in velvet for their antlers. He narrowly escapes with his life, but follows the smugglers to Portland. 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.
