On the border of Daliang Kingdom, there is a secluded village locked in black fog. It is isolated from the outside world all year round, like a secret realm abandoned by time. In the simplicity and tranquility, the villagers guard the unknown secrets and legends - the ancient forest behind the village is filled with gloom on full moon nights, the wind sounds like the roar of hungry wolves, and creepy screams are often heard in the forest. In the mysterious noise, the desperate cry for help "Oh, save me, no" is intertwined with the sound of gnawing, which is frightening. As the story progresses, the terrifying truth behind the taboo is quietly tearing apart the peaceful appearance of this paradise. A battle about survival and unknown fear slowly begins between the secluded village and the mysterious forest.
