She signs her first autopsy report in the crematorium, only to find a birthmark in the dead person’s palm that matches one from her childhood memories. Forensic pathologist Shen Zhao uses science as her blade, cutting through layer upon layer of lies, unaware that she is stepping into the heart of an unsolved series of murders from twenty years ago. Detective Captain Jiang Lin relies on her reports to solve cases, while secretly tracking every detail she avoids. Intern Chen Yan quietly recreates the palm prints of the dead, while the old stoker Lin Huai’s furnace has burned the names of countless people who were never meant to be spoken of. When reporter Zhou Tang’s farewell letter reveals a corner of the truth, Shen Zhao finally understands: what she has cremated is not a body, but the truth someone wants buried forever.
