The String Killer is notorious for the dozens of murders he has committed in the short time that he'd been at the top of China's Most Wanted list. Lay, a university student with a knack for finding clues and a hobby of studying and tracking serial killers, is on his case. When turned down by the police, he takes it upon himself to track him down. After weeks of investigating, it becomes obvious to The String Killer himself what he's doing, and reveals himself. After the initial shock, Lay is faced with a decision: take it back to the police, or keep it to himself?
