In 2207, a strange "memory virus" broke out in the super city "Stardome City" with full consciousness access-infected people will periodically lose their memory, from recent trivial matters to identity recognition, and eventually become "blank people" who only understand basic instructions. Former memory data security engineer Lu Cheng accidentally discovered in the process of tracking down his missing girlfriend that his brain could "capture" the memory fragments left by the virus, and even reorganize the fragments into an accessible "memory illusion." In order to awaken his girlfriend whose consciousness has been devoured by the virus, he must sneak into the layers of memory mazes, fight against the "Deep Brain Group", the technological oligarch who controls the virus, and uncover the dark truth about "memory colonization" and "consciousness monopoly" behind the virus.
