The Heroic Trio

Someone is kidnapping all the male babies in the city and the police have no clues. It turns out that a Dark Master of the Underworld lives in the sewers and is taking them. He needs them because they were all born as potential Emperors, and he needs the future Emperor if he plans to take over China. The police eventually enlist the help of superheroes Wonder Woman (Anita Mui) and Thief Catcher (Maggie Cheung) to stop the evil fiend.
Against the two heroes is Invisible Girl (Michelle Yeoh), who's working for the Master and is assigned to watch over a young scientist (James Pax). The scientist is trying to create an invisible robe and Invisible Girl is supposed to kill him when he's finished. It turns out that the three women have a previous connection. Thief Catcher and Invisible Woman knew each other when Thief Catcher lived in the underworld but ran away ten years earlier. Wonder Woman and Invisible Girl knew each other as children but were separated when Invisible Girl left to live in the underworld. It turns out that Invisible Girl is not as bad as she seems. She's actually a good soul who's simply taken the wrong path. To redeem herself, she decides to help out the scientist and joins with her fellow superheroes to defeat the Dark Master.
The supernatural fight sequences choreographed by Ching Siu Tung (A Chinese Ghost Story) are dark, violent and bursting with creative energy. Of particular note is the train station scene, which features the most creative decapitation weapon ever to be wielded by a demon (played via grunts and growls by Anthony Wong). The production design is also worthy of note, as the city is not necessarily Hong Kong, but more of fictional Gotham City-type place. The score is catchy and boasts a theme song by Anita Mui. However, the largest reason this film works is because of the three female leads. Each is given a chance to shine both in the action scenes as well as the dramatic ones. It's clear why the three are considered three of Hong Kong's top female stars.
The artificial trappings tend to make the film feel set-bound and it's clear that there was a limited budget involved, but none of that takes away from the overall entertainment value of The Heroic Trio. There is also a sequel to the film titled The Executioners. (Magicvoice 2002)
