Zhou Mo grew up in an orphanage and knew nothing about his family until an inheritance letter led him to an old house in a remote mountain village. As the last bloodline of the Zhou family, he stepped into the ancestral home that had been dusty for seventy years, only to find a mahogany coffin in the basement that was engraved with ancient runes - it was as cold as iron, and there was a human-shaped outline like molten gold on the coffin lid, as if something had been "branded" inside.
The moment Zhou Mo touched the coffin, nightmares followed: the sound of knocking on the coffin in the middle of the night, the blood seeping out for no reason, the strange runes appearing on his arm... What is even more bizarre is the sudden visit of Lin Yuqing, a mysterious girl who claims to be a folklorist. She seems to know the dark past of the coffin and the Zhou family well. The old man in the village kept it secret and only warned him: This coffin can "eat people", and Zhou Mo's bloodline is the sacrifice it has been waiting for for many years.
As the full moon night approaches, the being in the coffin becomes more and more restless. Zhou Mo must uncover the truth about the bloody ceremony in 1945 - the five missing children, the twisted family contract, and the cruel fate that his father Zhou Mingyuan fought so hard to hide. When the boundary between the living and the dead is torn apart by the blood nightmare, the only price that can end the curse may be to sacrifice one's own soul...
