Alex, an intelligent but somewhat naive graduate chemist/educator, pursues a relationship with Chinese women (a special one). To his surprise, each China doll seems to be interested in sex very quickly. But sex with any of them is a lure to a fairly quick death by acquiring a deadly strain of syphilis which only affects Caucasian men. Each doll encountered is a carrier of this contagious and deadly disease passed on only through intercourse. The backup plan is to physically eliminate the men by force if the disease can't be implanted in a short period of time. Having encountered this scenario multiple times, Alex enlists the aid of his karate brothers to find out why the Chinese want him dead. He and his karate brothers (the kyokai) end up going to China, Tibet, and Nepal to stop what is the China Doll Conspiracy. Teams of two or more men each task themselves to destroy this conspiracy in a mission called "Dragon Slayer." The termination of the China Doll Conspiracy takes them from a small New Jersey town to places like Beijing, Hong Kong, Kowloon Bay, and Lhasa through four Asian countries. The success of their mission is dependent on their skills as martial artists. This is a mission to save America from the CCP of the PRC who use smuggling fentanyl and Chinese women as their implements of destruction. The fate of America rests in the hands of a few karate black belts.
