One hundred days before the college entrance examination, Zhou Xu saw Lin Zhiwei in the class photo - a girl who was clearly standing in the photo but not at the scene.
The strange thing is that everyone in the class admits to having seen her, but no one admits that she belongs to this class. Some said she was just here to participate in competition training, some said she was just passing by, and some produced a "Lin Zhiwei's Autobiography" to prove that all this was just a misunderstanding deliberately created by her.
Zhou Xu originally wanted to find out the authenticity of the photos, but during the investigation, he kept discovering that he was being written into a new description. What made him even more unable to escape was that the name Lin Zhiwei mentioned was Tang He, the missing student from the previous class.
The testimonies of the year, the reorganized materials, and the version that the class chose to believe gradually pieced together an uncomfortable fact: it is not that some people have not seen the truth, but have already learned how to make everyone believe another answer.
But this time, Zhou Xu must answer first - is he a witness or the next criminal created?
