Heroes of the East 1978

A-To—the young son of a wealthy industrialist—is set to marry the daughter of his father’s business partner, a Japanese woman, even though he has never even seen her before. However, the young woman turns out to be a true beauty, and A-To immediately arranges the wedding. However, he failed to take into account “certain” cultural differences, and already in the first days of their “honeymoon,” Kudo (as the Japanese woman is called) begins breaking down the walls of the house while practicing traditional Japanese karate. After arguing with her over differences in martial arts, A-To insults her, and Kudo returns to Japan. Immediately, seven masters of various styles arrive, burning with a desire to avenge the insult to the honor of their entire nation and to determine once and for all which country’s martial arts are the most effective.
