Folklore reporter {Su Wan} took over the bizarre midnight suicide case and accidentally discovered a dusty videotape. After playing, the strange female figure and the harsh ringtone drew her into a death curse - she would die if she couldn't find a way to break it within seven days. Objects in the house shift, dark shadows flash in the mirror, ringing rings in the ears, and supernatural events follow one after another. Following the clues, she discovered that the video tape was closely related to the arson case twenty years ago, and the woman was the victim who died unjustly. In order to protect herself, Su Wan ran around the corners of the city, piecing together the truth amidst fear and danger, and finally found the woman's remains, uncovering the secret of her frame-up, resolving the curse with sincerity, and bringing to light the real murderer who had been hiding for twenty years.
