When lawyer Wen Zhiyuan was defending a bizarre autopsy case, he accidentally discovered a familiar signature at the end of the report - it turned out to be his father who had lost contact since childhood. At the same time, forensic expert Jiang Wangshu was assigned to assist in the investigation. Her calm and sharp analysis pointed out that the report had been tampered with. The two were forced to cooperate due to the case, and the truth was revealed layer by layer, but it involved a medical scandal that was deliberately buried twenty years ago. The shadow of Wen Zhiyuan's family intersects with the mystery of Jiang Wangshu's life experience. Trust and betrayal are intertwined inside and outside the court. And that signature may not only be a relic of father's love, but also a judgment set by fate.
