Lin Mo, who had just graduated from the police academy, joined the Criminal Investigation Detachment of the Municipal Public Security Bureau with a passion for criminal investigation. However, on his first day on the job, he accidentally awakened to the "criminal record system" - he could see the red numbers above everyone's head that represented the seriousness of the crime. From then on, he started a unique path to pursue the murderer.
The unknown body of a man found in an abandoned textile factory in the suburbs, a robbery and murder case in the courtyard of an old machine tool factory, a series of shop thefts that had been buried for five years, and the shadow of serial sexual assault that had been hidden for nine years... Faced with one difficult case after another, Lin Mo relied on the "crime value perspective" ability granted by the system to lock down suspicious targets. He also unlocked key skills such as "trace recognition enhancement", "logical deduction acceleration" and "criminal psychological profiling" through the points accumulated from solving the case.
From discovering fiber scraps and metal residues that ordinary people ignore during on-site investigation, to connecting the suspect's behavioral logic through subtle clues, and then breaking through the psychological defense line to make the real murderer confess his crime. Under the leadership of veteran detective Zhang Tao and the trust of detachment leader Li Jianjun, Lin Mo used his extraordinary ability and solid criminal investigation skills to tear apart the disguise of crime time and time again, so that the injustice can be vindicated and justice will no longer be late.
