In search for her perfect groom, Sit (Tang Bik-wan) goes to a bordello and falls in love with talented Lee (Mak Bing-wing). Burning with jealousy, the Imperial Tutor's son (Siu Chung-kwan) frames Lee for treason, yet accidentally gets killed by Sit when she rescues Lee. To avenge his son's death, the Imperial Tutor tricks the couple into joining force in overthrowing the emperor and plans to accuse them of treason. Sit, who turns out to be the emperor's long-lost daughter, follows Lee to the palace for investigation. In the film, Tang Bik-wan put on various guises in her character, e.g. dressing as an ugly and Zhongshan dialect-speaking woman when she weds, disguising as a man while investigating. She proved herself a well-rounded diva with her marvellous singing, switching between different dialects and operatic styles. The scenes with Mak Bing-wing also show great chemistry, as the duo evolve from quarrelsome lovers to husband and wife.

Chun-hong's identity is unveiled when she devotes herself to helping the refugees of a disaster by distributing food and emergency supplies. Ba-hung would like to murder Chung-hong by hanging, yet it ends in him being killed by his followers.
