Lu Zhe, a talented young man recommended to Peking University, became the public enemy of the whole school overnight. His classmate Zhou Tao reported him for cheating on the college entrance examination, and the police even identified him as the murderer based on DNA evidence. The social network sentenced him to death, seemingly with irrefutable evidence. But Lu Zhe didn't take the college entrance examination at all! He used surveillance, timelines, and witness loopholes to uncover lies step by step. As the investigation deepens, a black hand manipulating politics and business emerges. Its real purpose is to seek revenge against Lu Zhe's father for twenty years. When everyone thought the dust had settled, the mysterious "Scavenger" plan was quietly launched, and a larger chessboard was laid out at Lu Zhe's feet.
