Anita Mui is Wonder Woman, who's married to cop Damian Lau by day. By night, she straps on a mask and takes to the rooftops. Maggie Cheung is Thief Catcher, a tough-as-nails mercenary who offers to find the bad guys for bucks. Michelle Yeoh is Invisible Girl, who starts off as a lackey of the eunuch but eventually sees that she doesn't have to follow such a dastardly fellow. Besides, she didn't turn on the evil eunuch. The movie film would be called Heroic Duo. Invisible Girl, which sounds like the title of a Marvel Team-Up comic book. Starring Anthony Wong as the mute, beast-like Kau.

The Heroic Trio has great action courtesy of Ching Siu-Tung, the story and cinematography are enjoyable in an urban fantasy sort-of-way. However, the film detours near the end for some disturbing violence that's far from necessary. What actual happens to kids and babies???? Gone missing and kinapped by who ???? An uniquely Hong Kong motion picture and practically required viewing.
