Demons were rampant in the Tang Dynasty, and a small fishing village invited a Taoist priest (Feng Mianheng) to exorcise them because of the suffering of the fish demon. The young exorcist Chen Xuanzang (article) came to help but was mistaken for a liar. Fortunately, Miss Duan (Shu Qi), a professional bounty exorcist, helped Xuanzang subdue the Fish Demon (Li Shangzheng). They meet again in Gaojiazhuang, and subdue the pig demon pig (Chen Bingqiang). This exorcism was unsuccessful, but Miss Duan fell in love with Xuanzang at first sight. Xuanzang turned to Master for help and learned that the way to exorcise demons was to turn to the Monkey King (Bo Huang) who was trapped under Wuzhishan. So he went to Wuzhishan, and met Miss Duan and her five evil spirits on the way. Miss Duan even tried to be with Xuanzang, but she was repeatedly rejected. Under the guidance of Fourth Sister (Chrissie Chau), she tried to be more feminine, but it backfired. After breaking up, Xuanzang went on his way alone, and at the same time, the demon master (Yan Neng), the wild silkworm horn () and kong xu gong zi () also went to exorcise demons.
