Casey Bowman's life of domestic happiness is broken by a violent act of violence, prompting him to adopt the survival rule of fight everyone and trust no one. With the assistance of a shrewd and cunning sensei, a daring American vowing vengeance tracks the murderer from Osaka to Bangkok to Rangoon. His sole leads were a series of victims whose necks bore the unique mark of barbed wire strangling. Casey must hone his razor-sharp reactions and elevate his combat talents to the next level, even if it means faking his own demise through intense meditation. His objective is the evil drug king Goro, who is flooding the streets with lethal meth manufactured at his remote jungle factory. To prepare for his ultimate confrontation, Casey must become a Ninja-worthy invisible warrior. But just as Casey has cornered his prey, an unforeseen turn of events reveals that his war is only beginning: he cannot trust anyone.
