The "shady steamed bun shop" in the deep alleys of the old city never opens in a sunny place, and its business always becomes weird after dusk. Lin Mo, who came to search for his missing cousin, stepped into this alley surrounded by thick fog for the first time. He was entangled in the vague smell of blood in the shop, the familiar fragments of schoolbags in the corner, and the swollen and white face of the shop owner.
As the investigation deepens, she discovers that this steamed bun shop not only hides the secret of missing people, but is more like a dark hub connected to a network of trafficking, fraud, and pyramid schemes. The motorcycles transporting goods late at night, the sound of struggling in sacks, and the figure flashing for help behind the second-floor window all hint that this is no ordinary shop.
