In Xinhai City, where memories can be extracted, stored and traded, Lu Zhou, a top memory restorer, works with fragments of broken consciousness all day long, just to find the key memory that awakens his wife who fell into a deep coma due to an accident. A mysterious woman codenamed "Zero" came to his door with a completely formatted memory chip, asking him to restore a forbidden past. When Lu Zhou dived into the abyss of this violently erased memory, he discovered that the secret of "Zero" was bizarrely intertwined with his wife's accident. In the maze woven by technology, every step of exploration may lead to the light of the truth, or it may lead to a trap that will never be recovered. He must salvage the only island in the ocean of forgetfulness for his love and himself.
