In Xinjing City, memory is the last luxury and the most dangerous commodity. "Memory Stalker" Yan Jin's job is to sneak into other people's abandoned memory data streams to find forgotten values. When he accepted a commission to retrieve the memory of a lost diamond, he saw his own face that he should have long forgotten in the target's memory fragments. A non-existent key, a ghost program called "Silver Wings", drags him into a huge lie spun by the technology giant "The Realm of Immortality". In order to find the truth, Yan Jin must travel through the maze of reality and memory, and while fighting the pursuit, he must piece together the erased and true self.
