Han Mo has been able to see "things" ordinary people cannot since he was a child. This ability brought him endless trouble, and things improved only after he learned to control it. Recently, however, his power suddenly grew stronger, and he began seeing even more terrifying things.
Han Mo receives a commission from his old classmate, Lin Yu, to investigate strange phenomena at the old home of Lin Yu's uncle, Lin Shicheng. The payment is generous, and Lin Yu promises to provide clues about the "yin-yang eyes" Han Mo has been searching for.
Han Mo and Lin Yu head to the Lin family's old residence on the outskirts, a three-story building from the Republican era. As soon as they arrive, they feel an intense, bone-chilling presence. The door unlocks by itself, as if offering them an unsettling welcome.
Inside the old house, Han Mo sees a horrifying sight in an antique dressing mirror: the room reflected in the glass is unlike the real one, covered in bloodstains, and a little girl in red begs him for help.
During the investigation, an invisible force suddenly grips Han Mo by the throat, nearly suffocating him. At the critical moment, he uses his ancestral copper coin talisman to save himself, while hearing the little girl warn him, "Get out, now."
Lin Yu reveals that a massacre once took place in the house, but he is evasive about the details. Han Mo realizes that he may have become entangled in a supernatural incident far more complicated than it appears.
