Sam Borne is a man of East and West—a man of great refinement and raw power, with the great skill and death-craft training of the ninja. Now the committee is sending Borne back to Vietnam, where a rogue army general calling himself Doctor Sun Sun is the overlord of a horrific armed heroin factory—using the forced labor of American POWs. Borne must get close enough to terminate the grotesque Dr. Sun Sun—and smash his plot to flood the US with heroin. But Borne will be forced to improvise for his life, with the help of a beautiful woman and his own extra-human training. Borne is going against all odds: one man against a private army out to sow the seeds of evil in America.
