The Jianghu sorcerer Mao Shanming (played by Ng Man-tat) is not good at magic, but he has a lot of tricks. He often takes Dabao (played by Lu Fang) and Xiaobao to cheat for food and drink. When he was exorcising ghosts for the wealthy Tan Baiwan, he encountered a fierce ghost and fled overnight. Late at night, Mao Shanming broke into the quiet village. At that time, the village was harassed by evil horse thieves and was on high alert. Mao Shanming was mistakenly captured by the security captain (played by Lau Nam-kwong) as a horse thief. Fortunately, Taoist priest Jiushu (played by Lam Ching-ying) appeared in time to escape. At this time, the horse thieves arrived, and after a big battle, the villagers successfully repelled the horse thieves. Due to a dispute, Dabao and Xiaobao were taken away by Jiushu. Mao Shanming realized the truth that humans and ghosts are different, and decided to break up with the two ghosts, but Dabao was captured by the horse thieves who were good at magic...
