In the attic at the end of the old night market, the female teacher Dong Yajing died mysteriously and tragically. Mysterious numbers were carved on her ribs. The old street was filled with rotten stench and the aroma of garlic that night. Shen Yu was ordered to investigate, but found that the body was moved in the middle of the night, the time of all witnesses was inexplicably half an hour different, and each suspect loved to sing the nursery rhyme "Little Star" - three strange incidents revealed a corner of the truth. The silent deaf-mute piano player in the night market, the bells in the clock shop, and the old photos of the baby all point to the secret cry and disappearance of the baby twenty years ago. As the wonton stall steams up, the broken gears bring more clues. Shen Yu and his assistant Tang Zhu peel off the cocoons and uncover the tangled mystery of the town's years of resentment, memory and redemption.
