In 1940, Shanghai was in turmoil. On the edge of the French Concession, stands a forgotten old Western-style house - "Qixia Mansion". It was once the golden house of a certain warlord, but a bizarre tragedy occurred ten years ago - the mistress of the house, Su Wanqing, threw herself in front of the huge full-length mirror on the second floor of the mansion on a full moon night. Her death was strange and the mirror shattered. Since then, the mansion has been shrouded in horrifying rumors: a woman's figure will appear in the mirror late at night, sighs will be heard for no reason, and the people who live in it will range from crazy to mysterious deaths or disappearances. The mansion changed hands several times, but was eventually left dusty because no one dared to live there. Ten years later, the inheritance issues surrounding this haunted house have revealed dust-laden secrets and also attracted uninvited guests.
