There's savagery and plenty of it when a yankee gangbuster from the U.S.A. heads to the far east to penetrate a secret society, ruled by the ruthless Tong Father, Chiang Shan the Godfather of Shanghai. The government suspects Chiang has been shipping huge quantities of high grade narcotics back to the mob in the United States. The Tong Father cannot allow the U.S. government's agent to succeed with his mission. All of the Tong Father's merciless crew attempt to hunt the U.S. agent to his extinction, with the final vicious confrontation taking place between the U.S. agent and the Tong Father.
