Perfumer Lin Wanqing inherited an ancestral Feng Shui shop, but was involved in a series of murders. There is a mysterious fragrance left at the scene of each case, which is exactly the same as the "sense of death" left by her deceased mother in her memory. Interpol captain Gu Chengze suspected that she was related to the case, but during the joint investigation, he discovered that the two were actually responsible for the same murder case that killed a family twenty years ago. When Maoshan Taoism meets modern criminal investigation, can they uncover the thousand-year curse behind the fragrance?
