Blind detective Su Xiu Niang uses a sandalwood cigarette holder as a blade and uses her sense of smell to decode the bloody code in Shanghai. The case of his father falling from a building implicated the Qinggang drug network, the singer's jade brooch concealed Morse code, and the "JS" engraved on the police sergeant's pen turned out to be the code name of an international drug trafficking organization. When the gramophone "Rose Rose I Love You" becomes a fatal code, the sudden awakening of Su Xiu Niang's right eye will reveal the truth about the depravity of the student leader twenty years ago before dawn on the Huangpu River. Every wisp of jasmine is a fatal trap, and every character is a chess piece on the chessboard of the times. This is not an ordinary detective story, but an ukiyo-e of the Republic of China written with smell.
