Lin Shen, the cemetery administrator in the futuristic city "New Chang'an", discovered that there were living people in tomb No. 0715 While on duty. After entering, he encountered the trapped poisonous lawyer Su Wan. The two were forced to cooperate in order to escape. During the process, Su Wan used his legal knowledge to complain about Lin Shen's "mausoleum guarding skills". Lin Shen used cemetery tools to perform small pranks, and gradually discovered the "living tomb plan" of Zhang Cheng, the person in charge of the cemetery, which disguised the lower-class people who could not afford houses as dead people and imprisoned them in tombs to save city resources. In the end, the two used cemetery surveillance to expose the truth and brought Zhang Cheng to justice. Lin Shen resumed his status as a civil servant and left an ambiguous agreement with Su Wan.
