A wealthy man enters a sham marriage with straitlaced Cheng Tai-Nan (Kara Hui) to keep his estate away from his greedy brother. After her husband's death, Tai-Nan inherits the property and meets the rest of her in-laws, including a handsome cousin (Hou Hsiao). But as they fall in love, the evil brother steals the deed to the land. Tai-Nan must find the courage to defend her claim -- with flying fists and feet -- as the rightful heir.
