Three years after Lin Ye, a former key criminal investigator, "retired", he was re-involved in the "Zhang Jianguo Unjust Case" that caused the collapse of his career by a mysterious phone call. The mysterious man used clues as bait and led him to the abandoned paper mill, starting a dangerous game to find the real murderer and vindicate Zhang Jianguo.
Intent: Personal redemption: Lin Ye faced professional stains with a self-punishing "retirement", and finally achieved spiritual redemption by actively pursuing the murderer. Dilemma of justice: The tampering of evidence in the case and the impunity of the real culprit reflect the conflict between "procedural justice" and "consequential justice" in judicial practice. The game of human nature: The motivations of the mysterious man, the ruthlessness of the criminal gang, and the persistence of Lin Ye are in contrast, showing the complex human nature where good and evil are intertwined.
