There is a rule at night in the old market: do not look in the mirror three times after the rain. Because if there is a face missing in the mirror, that person will disappear from neighbors, relatives, friends, files and debt slips the next day. Even the creditor will not remember that he once owed money. It sounds very happy, but in fact, he usually has died in an unseemly manner.
Wen Deng is the most unscrupulous temporary secretary of the night watch office. He looks after his sister's pawn shop during the day and runs errands for his down-and-out master at night. His specialty is talking back, borrowing money, and pushing trouble to tomorrow. Until Bai Zang, the leader of the Baixiang Opera Troupe, came to the door holding a soaked photo album, saying that an actor had been disgraced, and the last page of the album had Wen Deng's father's old name written on it.
From the testimony at the roast pork stall to the headless figure in the rain alley, from the disappearance of the theater troupe to the closure of the municipal disaster department, each case can be solved independently, but it also drags away the Wen family's old debt from twenty years ago. Wen Deng finally understood that the old city was not hiding the monster, the old city itself was keeping accounts for the monster.
