Bat Girl (Josephine Siao) returns from Singapore to Hong Kong as the singer Barbara to investigate her dad, a trapeze artist’s death. She is orphaned. She stays with her aunt. Her cousin is Sze Wai (Lui Kei), a pulp fiction writer of the superhero, Bat Girl. Encountering injustice, Bat Girl confronts Sze to interrogate about the whereabouts of Wu Wan-Lung (Sek Kin). Bat Girl unites with her friend, Chan Kwong-ying (Lydia Shum). Sze tracks down Bat Girl and is involved in a fight with Lung's marksmen in a nightclub. A private detective, James Bond (Cheng Kwun-Min) helps Lung find Bat Girl to no avail, as she appears in guises. Bat Girl eavesdrops on Lung and realises he was her father's murderer. She revenges on Lung, and a strange female creature (Yung Yuk-yi) appears as the Lung's house's owner. The creature finds that Bat Girl is her daughter. She wrestles with Lung and they are both burnt to death. At last, Sze finds out that his cousin is Bat Girl and they begin a romance.
Directed by Wong Fung, The Lady Killer leans on a strong ensemble — Josephine Siao Fong-Fong, Lui Kei, Cheng Kwun-Min — to carry a story that balances spectacle with character.
The film landed with audiences for its craft and performances, and remains one of the most talked-about action titles of 1967.
