In order to take care of the elderly body of the third wife, Uncle Feng (played by Lin Zhengying), who was a policeman in Tung Ping Chau, came to cooperate with the police investigation. Uncle Feng is a policeman with strong magic. After looking at the corpse, he found something strange in it and suspected that someone was using the walking corpse to transport drugs. Uncle Feng's old partner (played by Wu Ma) knew that the case was serious, so he asked Uncle Feng to investigate.
