In 2000, Linzhou, a small southern coastal town, fell into panic. A series of serial rape and murder cases occurred one after another. Dozens of single women were killed on their way to get off work late at night. The murderer would always leave cigarette butts at the scene after committing the crime. He was arrogant and cruel. Wen Hao, who had just graduated from the police academy with excellent grades, was assigned to the Linzhou Criminal Police Team with his enthusiasm and ideals for criminal investigation work, just as the case entered a heated stage.
In this serial case that spanned several years, the third victim, Lin Qing, was the only survivor. The murderer accidentally missed when committing the crime. Although Lin Qing escaped by chance, it left an indelible psychological shadow. In order to uncover the murderer and protect more people, she overcame the trauma and entered the police academy.
