Mr. Wong and his students take shelter in a house during a storm, where the caretaker, Uncle Fook, tells a ghost story. Long ago, cousins Bai Yunfeng and Bai Deqing rescued a singer, Qin Chuxiang. Both loved her, but Chuxiang only loved Yunfeng. Deqing, jealous, convinced Yunfeng’s father, Bai Yinzong, to break up the couple by arranging Yunfeng’s marriage to a cousin. However, Chuxiang was pregnant, so the Emperor agreed to their marriage. On the wedding day, Chuxiang’s mother revealed that she and Yunfeng were siblings. Deqing then bribed locals to accuse them of incest, and they were nearly drowned. Mr. Wong’s group realizes Yunfeng and Chuxiang survived and had pretended to be ghosts for years. Yinzong exposes Deqing’s plot, and Yunfeng and Chuxiang finally marry.
