The story is not only about "revenge and redemption", but also deeply explores the eternal proposition of "intergenerational transmission of trauma" and "finding light in darkness". Gong Fu chose to face his trauma and eventually became a healer; while Wu Bai was swallowed by trauma and became a new perpetrator. Gong Fu is responsible for reading the logic from the silence of the corpse, while Wen Xu senses the motivation from the world of the living. One tells you "what the murderer did" and the other tells you "why the murderer did it". Forensic doctor and criminal psychologist Gong Fen returned to China, ostensibly to assist the police in solving a series of unsolved cases marked with the "Z" mark, but in fact to track down the murderer of his father twenty-five years ago. During the cooperation with the sunny and passionate criminal police captain Wen Xu, the two formed a deep friendship. They found that all the cases pointed to a highly intelligent criminal hidden behind the scenes, Wu Bai. Wu Bai is both a victim of childhood trauma and a "judge" who uses psychological knowledge to create evil. In the end, with Wen Xu's help, Gong Fu not only brought Wu Bai to justice, but also completed his own redemption and decided to spend the rest of his life healing those injured souls.
