Hocus Pocus (1984) Inspired by the paranormal stories of opera veteran Master Sheng (Ching-Ying Lam), an opera troupe, which includes the daring actor Kuei (Wei Tung), trick each other with ghostly stories and horror tricks. The troupe is repulsed by the overly-confident opera actor Chia (Ho Kai Law); therefore, they play the ultimate ghost trick on him. When Chia finds out, he confronts the troupe, resulting them in keeping a distance from each other. However, the troupe's troubles worsen when their opera stage is haunted by a mischievous and restless ghost (Yuet Sang Chin).
