Let me preface this review by saying that this film has numerous fantastic martial arts scenes. The ingenious script allows for a wide variety of Chinese and Japanese martial arts to be displayed. The kung fu is among Liu's best, and this film his most action-packed.
Now....the essential plot of this film has a Chinese man and his japanese bride, both martial artists, disagree over whose country's arts are the best. The disagreement leads to a misunderstanding, on the part of her Japanese family, who send a group of fighters to beat her husband, played by Gordon Liu. Liu defeats each of the Japanese fighters' unique styles with a different, counter-acting kung-fu technique. In the end, he brings the misunderstanding to an end. No one is killed.
This film is often cited as being one of the few to treat japanese and chinese martial arts on the same level, giving equal respect to each. well, this is not true. In fact, there is alot of hypocrisy in this film. Being a Hong Kong production, one can understand that the Chinese characters will be portrayed in a more favorable light. Many critics take the fact that since no blood is spilled and there's understanding and harmony at the end, that connotates a favorable depiction of the Japanese. The Japanese ae portrayed as brutish, rash, and sometimes clownish; their martial arts unrefined. Gordon Liu is presented as graceful and stoic.granted, it's not as entirely unfavorable as many HK martial arts films are, but it definitely does not show the equality of japanese and Chinese martial arts. Note how the Japanese wife dresses in Chinese garb by the end of the film....
What I do think is interesting about the conflict in the film is how Liu places the Sino-Japanese strife and misunderstanding within the context of a marriage. Liu often uses the inversion of roles of man and woman in his films, it was odd to see that this film was so conservative in that regard..
