Hong Kong action specialist Wong Jing wrote the screenplay for the slam-bang Chiklo Dakgung (Naked Weapon). Madame M (Almen Wong) orchestrates the abduction of 40 different 13-year-old girls from around the world. She trains them as assassins, and in a few years, unleashes them on the world to do her bidding.
The most potent of the group turn out to be gymnast Charlene Ching (Maggie Q), kickboxer Katt (Anya), and Jing (Jewel Lee). CIA agent Jack Chan (Daniel Wu) has stayed on the trail of the girls since their disappearance. When he finally catches up to Charlene, Jack is nearly done in by her alluring but deadly qualities.
