“Yau Li” (Moon Lee) is sent to work undercover in a nightclub while investigating slave trafficking controlled by its owner “Chu” (Leung Kar-yan). His bodyguard “Michael” (Gordon Lau) watches her sing and becomes infatuated. His attitude to Yau Li understandably enrages his girl friend (Nadeki Fujimi) who also happens to be the boss’s daughter. Both Lee’s nightclub costume and Fujimi’s leather-clad “bad girl” outfit are noteworthy.
