Deep in the city where information is overloaded, there exists a rare profession called "memory sculptor". They can reconstruct other people's memories from fragmented clues and gain insight into hidden truths. Ye Su, a top memory sculptor, is infamous for his unique abilities. When a series of mysterious, seemingly unrelated disappearances rock the city, he becomes involved. The victims do not simply disappear; traces of their existence seem to be being quietly erased by some invisible force, as if they had never appeared in this world. Assisting Ye Su in the investigation is the calm and rational psychiatrist Shen Xi, a representative of the victim's family. As the investigation deepens, the two discover that there is a huge conspiracy to manipulate memory and perception behind the disappearance. Every time he reconstructs his memory, Ye Su gets closer and closer to the truth, and his own perception of reality begins to waver. When memory becomes the most unstable evidence, who can prove that they really existed? This is not only a journey to pursue the truth, but also a philosophical torture about existence and nothingness.
