This third installment of the popular softcore Category III Hong Kong exploitation series is a great deal less outrageous than Erotic Ghost Story II under the more controlled direction of veteran helmer Ivan Lai. Set in the Tang Dynasty, the plot concerns an engaged couple, Chu Chung and Liu Su-su, who encounter numerous fantastical adventures after meeting Reverend Wick (Shing Fui-on), a cleric who can shrink himself to the size of an atom. Exploring an abandoned shack, Chu Chung finds a painting which is a gateway to another world, where he meets three beautiful maidens. One of them, Yun I-meng (Pauline Chan), seduces him as part of an evil plot to overthrow the god Chia Yuan (William Ho). Chu is told that Chia Yuan is a rapist and had kidnapped I-meng -- lies which lead him to believe that the god is evil and murder him. The whole thing is being engineered by a female demon called Vixen, who wants to cannibalize Chia Yuan to obtain his powerful source of Yang energy. The repentant I-meng sees the error of her ways and helps Chu get back home to his world, but his beloved Su-su gets trapped in the other dimension, leading Chu and Reverend Wick to attempt a daring rescue mission. Chik King-man and Cheung Ching-wah co-star. ~ Robert Firsching, All Movie Guide
