In the "Mirror City" where memories can be erased and traded, Lin Feng, the top memory weaver, makes a living by erasing the pain of others, but cannot mend the hole in his own heart.

He discovered that a "ghost memory" in his client's mind that did not belong to him surprisingly overlapped with his dusty past. In order to pursue the truth, Lin Feng must dive into the abyss of consciousness, and under the double pursuit of official surveillance and mysterious organizations, piece together a secret that can subvert the entire Mirror City.
