Former criminal defense lawyer Chen Yan put on a legal cloak for the gangster Qingtenghui, but suddenly surrendered during a live broadcast of the court trial watched by tens of thousands of people, sparking national public opinion. Prosecutor Shen Zhao discovered the encrypted clues he left behind, including financial officer Lin Mu's account books, former judge Zhou Qishan's transaction recordings, and technician Xu Yan's live broadcast breakpoints, all connected one by one into a web of revenge. When the gang power began to fight among themselves, Chen Yan's true identity was revealed layer by layer - he was not an accomplice, but a buried witness. And Shen Zhao is standing on the edge of the cliff between law and justice, deciding whether to arrest him or become the last knife in his hand.
