After Li Daniu is beaten by village bully Wang Laosi for stealing waste copper from a brick factory, he accidentally stumbles upon the crimes of waste collector Sun Dezang—robbing an ancient tomb and burying a murdered body. He is silenced by Sun's subordinate Ergou, but continually reincarnates back to the day he was beaten. Through repeated investigations, Li Daniu discovers that Ergou is actually forced to fake being mute, and the two form a partnership. Using the endless reincarnation to repeatedly gather evidence and tracing the tomb-robbing and smuggling chain, they root out Sun Deshun, Qian Desheng, Wu Degui, and even the mastermind Chen Qiming. During this time, Li Daniu turns over a new leaf, stops stealing, and uses the information accumulated through reincarnation to work as a lost-property detective. Eventually, the entire gang is arrested, and the reincarnation ends. Li Daniu stays in the village to open a detective agency and remains with Zhang Cuihua.
