In the future city "Xinhai City" where technology can tamper with memory, Ling Chen, a top memory weaver, lives a life of isolation from the world, burdened with indelible trauma. One night, the mysterious woman Su Wan brings a bizarre commission: to reconstruct her late husband's last memory and find out the truth about the murder. Ling Chen was involved in a puzzle composed of broken memories. He dived into the chaotic depths of the deceased's consciousness, only to find that the ruins of this memory had already been trampled by others. Every flashback reflection may be a carefully laid trap; every forgotten detail points to a larger conspiracy. On this island of memories where true and false are difficult to distinguish, Ling Chen not only has to track down the murderer, but also faces the ghosts buried deep in his heart.
