Sup saved and raised up by a Taoist Yan since he was a baby. He then becomes his assistant in exorcising ghosts and demons when he grows up. Once he destroyed a scholar Tsui's house, he asks him to move to Yan's, where they live together and become good friends. Tsui then meets Mok Sau, a wandering ghost, who jumped down a cliff to death when she was robbed and humiliated by a ghost king on her way to wedding. They fall in love at first sight, and Tsui draws a picture of Mok Sau, putting it up in his room just for seeing her more often. In order to avoid the ghost king's pursuing, Mok Sau hides herself in the picture. However, she's driven away by Yan and then caught by the ghost king. Finally, touched by both Tsui and Sup, Yan promises to go to the hell to rescue Mok Sau from the ghost king. However, Tsui and Mok Sau finally become the figures in the picture as they fail to escape in time. (Joy Sales)
