A very old ghost film, which begins with the introduction of Ghost Festival on July 15 every year. In the middle plot, a boss meets a woman in a hotel.

The plainclothes policeman played by Wu Zhenyu is dirty in appearance and rude in behavior. Li Cansen, the protagonist of Ghost, is like a fool, and even the environment where the story takes place is disgusting. On the day of Yulan Festival, a male ghost came out naked to seek revenge from the policeman Wu Zhenyu, but he was afraid of his "ghost gun", so he became the girlfriend of the courier boy Li Cansen and told him to steal the gun. Finally, it proved that Wu Zhenyu was ugly, but he was a good policeman, and the male ghost was the real bad guy, so Qi Xin, a policeman and citizen, worked together to drive away ghosts.
