Psychological counselor Lin Wei's crime analysis live broadcast was invaded by a group of "all-knowing" barrage viewers. They not only revealed undisclosed details of the case, but also began to teach her how to solve the perfect crime - until one day, a barrage said: "The next victim is you."
Lin Wei is a consultant who specializes in criminal psychology and analyzes real cases on a live broadcast platform in his spare time. She is used to coding bloody scenes and only exploring the psychological maze of the murderer. Until one day, a group of mysterious viewers flooded into the live broadcast room - they used golden barrage to accurately identify the murderer, restore details of undisclosed physical evidence, and even related serial cases that the police were unaware of.
At first, Lin Wei thought it was a prank or an insider leaking information. But when she followed the barrage prompts and assisted the police in solving three unsolved cases, she discovered that these "barrage detectives" were mixed with real criminals, retired detectives, and even... Serial killers who were not caught seven years ago.
And the audience member codenamed "Mirror" always sent her key clues when she was most confused, and his tone was as calm as if he was instructing an apprentice. Until a copycat crime was committed, the barrage suddenly flooded the screen: "He is at the scene, watching your live broadcast."
The police intervened urgently, and criminal investigation captain Gu Zheng forcibly closed the live broadcast room, but found an even more shocking fact in the background data: the IP address of the most active "barrage instructor" pointed to the scene of the crime every time.
