——When the tide erases the footprints, the evidence will still remember where people came from. ——[Criminal investigation suspense + case solving as the main focus + drama + double strength] Twelve years ago, the "July 19 Old Port Cold Storage Explosion" in Jinhai caused seven deaths and one missing. The official conclusion was that the accident was caused by internal strife among the smuggling gangs, but what was really burned were a batch of original account books recording human trafficking, drug testing, and power-for-money transactions. The mastermind behind the scenes secretly established the criminal network "Chaomen": with four layers of charity assistance, medical transfer, port cold chain and urban logistics as its shell, it trafficked people, laundered money and screened drug test subjects for overseas drug manufacturing groups.
The drug "Mist Blue" that Shen Ning has been pursuing undercover for four years is the end product of Chaomen. Every case she takes over after returning to the team is triggered by personal desires or fears. Not all murderers are members of the trendy society; however, the evidence buried in the case all touches the shell of the trendy society. As the evidence was closed layer by layer from physical evidence, testimony, and electronic data, Shen Ning discovered that both her father Shen Jianshu and He Changfeng's father Heshan had an unexplained relationship with the old port case files. The real problem is not just to catch the man behind the scenes, but how to bring a legal, admissible, and irrefutable chain of evidence to court without relying on the power of the fathers or being manipulated by the people behind the scenes.
