A Wokou who refers himself as the Nippon Ronin (Chan Hung-lit), colludes with the coastal local tyrants of Fujian and Zhejiang Provinces, along with cult religious groups.

Young warrior Fan Chen-tung (Kong Ban) leads a resistance group to retaliate which prompts the Chinese martial world to share the same hatred against the Japanese and tyrants.
