In the near future where memories can be read and repaired, Lin Mo, a top memory restorer, spends his days repairing other people's broken pasts, but he is unable to piece together the face of his deceased wife. That face is an eternal blank in his mind. A mysterious commission broke his stagnant life. A client asked to erase a memory about an accidental fall. When Lin Mo dived into the core of this memory, he saw the truth that he had been pursuing all his life but was extremely afraid of. It was not an accident, but a murder, and the victim was his faceless wife. The former restorer has now become the only witness and avenger. He must find his own island of truth in this sea of oblivion built of lies before his client can retrieve his memory.
