When police detective Zhou Ye investigates a bizarre fall-from-a-building case, he discovers that the victim had been secretly photographing him for three years. Even more frightening, the victim’s phone is full of photos of him with his “daughter,” even though there is no such child in his household register. Following the clues, he uncovers the truth about the virtual world and learns that he is a “Class Two Observer” whose memories have been erased. The only way to get his daughter back is to overthrow the rules of the entire System.
