After Chen Zhen's execution in Shanghai, the Japanese feared that his death would unite all Chinese kung fu schools against them. Fearing this, the Japanese gave orders to the head of the Hong Ku School, Miyamoto (Lo Lieh) to surpass all Chinese schools including the Ching Wu School. When they refuse, the Japanese beat up the students and destroys the school. Meanwhile, one Chinese learns about the destruction of the Ching Wu School when he goes to Shanghai to visit Chen Zhen's grave.
