Xu Mo, an antique appraiser, received the key to his old house from his late mentor's daughter, and stepped into a nightmare that spans a thousand years. The bronze mirror in the house will move, bleed, and even a "mirror image man" who looks exactly like him will crawl out at midnight. When Officer Zhou told him that "Shen Yu died three years ago" and when the hospital monitor showed that he had two hearts, Xu Mo discovered that he was trapped in a seven-day cycle - and this time, it was the eighth time.
