The criminal in the movie is a typical antisocial personality disorder patient. He grew up with his father's violence and had a difficult childhood with his older sister. In the third year of junior high school, he killed his father because he couldn't bear his violent behavior. The elder sister knew the secret and chose to protect the younger brother, which is reasonable. However, this secret caused the younger brother to become increasingly anti-social and commit multiple murders. Some of these cases have passed the deadline for public prosecution, and some are still under investigation. In the movie, Jiang Taiwu is a cold-blooded murderer with a high IQ. He looks friendly on the surface, but is very cruel on the inside. He learned a lot about criminal law and psychology in prison, so he has a strong ability in investigation and counter-investigation. It is difficult for ordinary criminal police to deal with him
