A Chinese man (Gordon Liu) and a Japanese woman (Yûko Mizuno) enter into an arranged marriage, but what begins as a happy union starts to unravel when their clashing styles of martial arts trigger a family feud. The husband must then prove the worth of Chinese kung fu in a series of duels with seven Japanese fighters. The sparks fly, and so do the swords, spears, kicks and punches in this playful entry from the Shaw Brothers catalog.
