The strong moral of this film is that, when vengeance is sought, both the innocent and the guilty suffer and die.
Only a little nudity. Ying lies weeping and naked in the cemetary after being raped. And later, a group of young lovelies cavort around while being filmed by one of the toughs. The Cat III rating is abundantly earned for violence.
You'll need a strong stomach to watch this film, although it is only moderately gory by HK standards.
Not a great film, but Pauline and Lam's performances are competent, and the interest never wanes.
