In the 23rd century, memories are no longer private treasures, but digital information that can be encoded, stored and even tampered with. Lin Xiao, a top memory restorer, is immersed in the daily life of repairing other people's broken memories. Until a bizarre mission, he discovered that there were unexplainable gaps and contradictions in his core memory. Lin Xiao's world began to collapse when a mysterious freelance hacker, Aaliyah, came to his door and claimed that his memory had been deeply modified by the "Cognitive Administration", the highest authority. In the fog of truth and lies, he must fight against a huge organization that controls consciousness, recover the stolen past, and reveal the shocking conspiracy behind his memory. This is not only a journey to find personal memories, but also an ultimate questioning about the freedom of consciousness and the nature of human beings.
