Trilogy of Hong Kong comedies.
A poet named Butterfly and her friend Kuen visit a stranger's mansion to return some possessions that were unintentionally taken. At the house, they stumbled upon an illegal weapons trade that ultimately went bad. To evade the police from interrogations, the two innocent witnesses wiped away their fingerprints and left a note that stated that the crimes were committed by "The Black Rose," who is known to be a fictional hero in a 1965 movie. However, a recovered fingerprint caused Kuen to be the prime suspect, and the apprentices of the Black Rose, apparently a real hero whose legacy was portrayed in the 1965 movie, attempt to seek the truth in the matter by confronting Butterfly.
Bumbling Hong Kong detectives Lui (Kenny Bee) and Leung (Tony Leung Ka-Fai) go undercover in an apartment complex to keep watch over Pearl Chan (Carina Lau), a high school teacher who is suspected to be connected to a rare diamond theft involving a notorious thief named Mr. Mickey (Simon Yam). Meanwhile, the legendary Black Rose (Veronica Yip) appears and is also in pursuance of Mr. Mickey, wanting him to surrender himself and the diamond in order to clear her name.

Lui Kei while trying to talk Black Rose into saving Tic Tac finally falls in love with her.
