A traditional Chinese legend comes in for lavish treatment in this (relatively) big-budget Hong Kong film. In the story, Ho is a scholar in Sung Dynasty (11th century) China. He has been given the task of making a finished copy of a religious text. It is a tantric sutra, and he is warned that evil spirits will attempt to steal the finished copy from him. One day, he encounters Lady Chuan and his lively daughter Cloud, and has a delightful love affair. In the end, he is appalled to discover that he has been consorting with ghosts.
