In 2149, humans realized the digital storage of memories through "neural mesh technology", and "memory reconstructors" became an emerging profession - they could delete painful memories, implant false fragments of happiness, and help clients get rid of psychological trauma. The protagonist Lin Ye is a top reconstructor in the industry, but during a mission, he discovers that the "happy clients" he handles have fallen into unconscious comas one after another. Behind this lies the conspiracy of the giant technology company "Memory Group": to control human consciousness by batch editing memories to maintain the "absolute stability" of society. In order to reveal the truth, Lin Ye had to use his "special ability" to shuttle through the maze of real and false memories, and fight against the "cleaners" who could tamper with other people's memories. In the end, in the process of saving others, he recovered his concealed original intention of "freedom of memory."
