Jiang Ye is the coldest criminal defense lawyer in the industry. He only speaks for the dead and never defends the living. He believes that corpses don't lie, but living people always hide the truth. Gu Tang is the loneliest silent person in the forensic world, able to read death testimony from the bones. When a murder case that was convicted by the entire Internet retracted its confession, the two men uncovered the bloody chain of the serial murder case during the court confrontation - the fibers in the deceased's fingernails, the abnormal distribution of the body spots, and the subtle angle of the broken hyoid bone were all the truth they spelled out with silence. The judge knelt down in court, not because of the evidence of guilt, but because Jiang Ye said: "You are sentencing a person, I am a dead person, and they haven't finished speaking yet."
