In the "Xinxing City" in the near future, citizens can implant perfect life experiences through the "Eternal Memory" service, thereby eliminating social uneasiness and restlessness. Lu Jin, as the top neural architect of the "Eternal Memory" company, has personally weaved dreams of happiness for countless people. However, his worldview collapsed when he discovered that the memories he had implanted into his clients began to show strange "cracks" - flashbacks of fragments that did not belong to any database and were full of pain and struggle.
In order to find out the truth, he is forced to cooperate with "Nightingale", a memory smuggler who wanders in the gray area. Nightingale trades "primitive memories" that are strictly prohibited by the government. These unfiltered true emotions and experiences are the only key to the truth, and they are also dangerous goods that can subvert the entire Nova City.
One is a creator wrapped in false happiness, and the other is a wanderer burdened with real pain. The two shuttle through the bizarre and dark corners of Xinxing City. Not only do they have to avoid the pursuit of the "Memory Supervision Bureau", but they also have to face a shocking conspiracy: How much of the erased real life has been covered up by the so-called "perfect memory"? And whose painful memories flash back point to whose forgotten cry?
