When the night is like a huge piece of black silk, quietly covering the streets and alleys of the city, evil also breeds and spreads under this dark night. Chen Mo, a senior detective from the Municipal Criminal Police Team, is wearing a simple black suit and his eyes are as sharp as a falcon, looking for clues to the crime in the darkness. He comes from a family of policemen, and the shadow of his father's death in the line of duty is like the hanging sword of Damocles, always inspiring him to defend the dignity of the law.
Chen Mo's opponent is Sun Batian, the leader of the criminal group. This man looked like an evil beast crawling out of hell. He was tall and tall, and the hideous scar on his face seemed to be the medal of his sin. He regarded the law as nothing and tried to establish his own evil empire in the dark corners of the city. He planned many robberies and smuggling cases, plunging the citizens into endless fear.
Chen Mo encountered many difficulties during the detection process. The betrayal of certain forces within the police station, like thorns hidden in the dark, constantly hinders his investigation. However, turning points always come at the most desperate times. His partner Zhou Yu is like a sharp sword that moves forward bravely. He still sticks to his post even after being injured, inspiring Chen Mo. Forensic doctor Lin Yue is like a bright light, relying on his professional ability to provide key clues to the case and help Chen Mo find a way to break through the bottleneck.
But the path to the truth is never easy. In order to uncover Sun Batian's crimes, Chen Mo had to break the rules and cooperate with informants, and he also paid a heavy price. Once obsessed with evidence, he began to wander on the edge of justice and morality.
