Michelle Yeoh (aka Michelle Khan) began her comeback bid with this flamboyant Hong Kong action film from director Michael Mak and choreographer Ching Siu-tung. Based on a novel by Ku Long, previously filmed in 1976 as Killer Clans, the film stars Yeoh as Sister Ko, part of the Happy Forest clan led by the dying eunuch Tsao. Before he expires, Tsao orders Ko and her friends to kill the head of the Elite Villa clan, Master Suen (Elvis Tsui), and steal a precious scroll. Yip Cheung (Donnie Yen) leads the first assault and fails, so Ko gets the skilled killer Sing (Tony Leung), whom she has a crush on, to help. Sing is engaged to Butterfly (Joey Wang), who has no idea that he is actually a trained assassin. When Sing infiltrates Master Suen's clan, he meets his childhood friend, Ho Ching (Yeh Chuan-chen), who is also working undercover for Sister Ko. Ho Ching's murder sets the stage for an angry encounter between Sing and Sister Ko, the final assault on the Elite Villa clan, and the revelation of a secret betrayal. Pop singer Jimmy Lin appears as Prince Cha; some of the fight scenes were later re-used in Chu Yen-ping's erotic Category III melodrama Slave of the Sword, which was filmed on the same sets later in the year.
