My Young Auntie

Why would a young martial-arts champion marry an elderly landowner? Jing Dai-Nan (Kara Wai Ying-hung) does it to keep his estate out of the hands of his greedy brother, Yu Yung-Sheng (Johnny Wang Lung-Wei). That makes her the new aunt to a household of relatives who are older than she is, and Lau Kar-leung puts her at the center of a family that would rather see her gone.
