In the "New Dome City" in 2149, humans have mastered the "memory embodiment" technology - able to transform memories in consciousness into "memory crystal dust" that is touchable and modifiable. The "Memory Administration" that rules the city claims that this technology is used to eliminate war wounds and cure mental illness, but in fact it maintains the dictatorship by tampering with collective memory. Lin Ye, who was once the top "memory catcher" of the Bureau, discovered that the truth about his wife's death had been tampered with. He defected with the stolen core technology and became a "memory restorer" who wandered the underground world, specializing in restoring the truth to victims whose memories had been tampered with. Su Xinglan, the new ace catcher of the Bureau, was adopted by the Bureau since she was a child and implanted with a false memory of "fighting for order". Her only mission is to hunt down Lin Ye and regain the stolen technology. The two frequently clashed in cat-and-mouse games, but gradually discovered that there was a strange overlap in each other's memories - the image of "fire ruins" that flashed repeatedly in Su Xinglan's mind actually matched the memory fragments of Lin Ye's wife's death scene. As the investigation deepened, they uncovered a shocking conspiracy spanning two decades.
