Description：Jiang Haodong (played by Ruan Zhiqiang), a section chief working for a government agency in Shanghai, is at the most critical moment of his life. The unit is considering candidates for deputy director, but he is impetuous and makes mistakes at work. His novelist wife Shu Mei (played by Dong Ping) is busy working on the suspense novel "Death Mystery" and neglects to take care of the family. The couple, who already have grudges, quarrel constantly. In addition, Haodong is obsessed with his old lover - who is also a mutual friend of the couple - magazine editor Lin Qianyu (played by Fu Chong). A peach blossom photo in an anonymous express delivery completely intensified the conflict between the couple. During the shoving process, Haodong was accidentally stabbed to death with a fruit knife. In panic, Shu Mei had to ask Qianyu for help in dealing with the body, but strange things happened one after another, and the deaths were confusing... This film is based on Shen Zuitian's novel "The Mystery of Death".
