Lin Jing is the top memory master in the city. With scalpel-like precision, he erases the painful past for his clients and gives them a false, white canvas of new life. He is calm and distant, and sees this job as a kind of atonement, but has never explored his dusty past. When a mysterious woman comes to his door with an incredible request, Lin Jing's stable world begins to collapse. She did not ask to erase the memory, but asked him to retrieve from the depths of his brain the truth about the "Great Silence" incident ten years ago that he had buried with his own hands. Forced to embark on a journey to unearth his own past, Lin Jing discovered that every forgotten fragment was like a sharp blade piercing the beliefs he relied on for survival. The shadow of the giant enterprise "Eternal Group" he works for is everywhere, and the truth he forgot is not only related to his personal salvation, but also may ignite this city built on lies. In the maze of memory, he must distinguish what is reality and what is illusion, and when the truth is enough to destroy everything, whether there is anyone worth saving.
