Hong Kong filmmaker Wong Chun-yeung directed this crime thriller which incorporates hitmen, amnesia, kickboxing, and a surprising amount of moral woolgathering into its convoluted plot showcasing three of the most popular Asian actresses. Moon Lee stars as Silver Fox, who has been raised along with her sister (Yukari Oshima) to be a cold-blooded killer by their uncle Fok (Eddy Ko). They have been trained to feel no remorse, but after one of their assignments ends with the accidental murder of some young children, Silver Fox begins to feel pangs of guilt which undermine her ability to be an effective assassin. When she and her sister are sent to Thailand in order to steal a computer disc containing incriminating evidence against Fok, Silver Fox receives a head injury during the mission. She wakes up with amnesia, and is taken in by the chain-smoking, masculine boxing manager Si Lan-fa (Sibelle Hu) and her dull-witted brother Rocky (Ben Lam). Unaware of her amnesia and convinced that she has betrayed him, Fok gives the order for Silver Fox to be assassinated, and her new friends must help her both survive and settle her accounts.
