Young writer Chen Mo moves into No. 44 Qingsong Road, an old Western-style house rumored to be haunted, in search of inspiration. Before long, however, he discovers that the house is hiding secrets no one knows about. Every midnight, eerie piano music echoes through the empty rooms. A female ghost in a white dress flickers in and out of sight in the darkness, while a mysterious diary and a rusted key seem to hold the answers to every mystery.
As his investigation deepens, Chen Mo meets his neighbor Lin Xiaoxia, and together they uncover a tragedy buried for ten years: Lin Xiaoxia's older sister, Lin Yuqing, died mysteriously on her wedding day, and her death is closely connected to a mysterious organization called the Shadows. The organization is not only tied to the house's curse, but also to several unsolved cases.
As they pursue the truth, Chen Mo and Lin Xiaoxia gradually discover that the secrets of the house are far more terrifying than they imagined. An ancient curse, hidden treasure, twisted human nature, and the Shadows' conspiracy intertwine into a vast web that ensnares them. Chen Mo's own past, it seems, is inextricably connected to it all.
