An imperial agent gets ridiculed for his various inventions, until his supportive wife encourages him to attend a conference, which's actually a trap to kill all the doctors serving the emperor, where his crazy inventions come in handy.

Set in Imperial China, Stephen Chiau plays Fat, a guard in the Forbidden City. But unlike his colleagues he doesn't know anything about Kung Fu or other martial-arts, because he uses his time to make futuristic inventions. So when the emperor is kidnapped and the world most beautiful geisha comes to town Fat has to use his brain to get things done.—<[email protected]>
