Jiang Qian, the owner of the late-night canteen, turns on the lights at 12 o'clock every night. He only cooks one dish - the one his guests most want to eat before they die. The police investigated him for three months and said he was a serial killer who specialized in killing people who ordered food. But no one knew that he could see that those "guests" still had knives stuck in their necks. When the ninth "guest" ordered a bowl of noodles with his own ashes, Jiang Qian laughed and cut off his own finger in the kitchen. With the siren outside the door, he whispered: "Don't worry, tonight's menu is the tongue of your criminal police captain." Wait, the fun has just begun.
