Late at night, fog erodes the borders of the dark forest like a tide. You Lan, a foreign scholar who is fascinated by the nature of existence, wanders alone in the forest, just to pursue the "Shadow Binders" passed down by the villagers - mysterious creatures that are said to be able to swallow memories and reshape people's hearts. She is not afraid of legends, just because her memory is incomplete and she longs to restore herself. However, when Youlan witnessed the strange rituals deep in the forest, she discovered that the so-called "shadowbinders" were not predators, but ancient wills waiting to be awakened, symbiotic with human fears. The darkness of the forest is not an external threat, but a mirror that reflects the cracks in the human heart. Youlan must face the most unspeakable desires and emptiness deep in her heart in order to break the cycle of fate. Every step forward is a self-analysis leading to the unknown, and every breath is a dance with the existence lurking in the darkness. This is a brutal battle about fear, memory and the meaning of existence.
