In the highly digitized and class-solidified "New Atlantis" city of the future, memory has become the most precious commodity and weapon. The male protagonist is a "memory hunter" who wanders in gray areas and is good at stealing, modifying or erasing memories; the female protagonist is the cool heir who controls a huge "memory bank" empire and firmly believes that the digitization of memory is the cornerstone of social progress. When the male protagonist receives a seemingly impossible task - to steal the female protagonist's deepest "core memory", he accidentally discovers that the female protagonist's memory has been carefully tampered with. A shocking conspiracy about the origin of the city is entangled with the two people's dusty past. They are forced to change from enemies to allies. In the process of tracing the truth, they not only have to fight against the mastermind behind everything, but also face each other's inner scars and completely different understandings of the nature of "memory", ultimately triggering a revolution about the freedom of human consciousness.
