Jiang Bo, the only surviving detective who had a cold case seven years ago, is now a criminal investigation profiler with a closed heart. A new serial murder case, the technique accurately reproduces the undisclosed details of the year. Along with the case comes the new forensic doctor Lin Xi - professional and calm, but with old scars that perfectly match the scene of his nightmare. She is living proof and a walking puzzle. When Jiang Bo was forced to partner with her, the truth burned between the bloody scene and the late-night autopsy table. She illuminated his way home, and he gave her a place to stay. This is a symbiosis that begins with suspicion, a redemption that is salvaged from the ashes of crime.
