In the cyber city "Xinjing" in 2242, memory diver Lin Wu is the ace of the police station. He can sneak into the last memories of the deceased and pursue silent clues. However, this technology also left him with an indelible trauma - the last sensory fragments of his deceased wife, haunting him like a ghost. When tech giant Evelyn Reed dies mysteriously on her "Throne of Memory," Lin Wu is forced to take on the difficult case. He dived into the abyss of Evelin's broken and twisted memories, only to find that it was not only a maze, but also a trap. A mysterious "data ghost" hunts him in his memory, and the boundary between reality and fiction collapses. In order to find the truth, Lin Wu must face his deepest fear, because the echo left by the murderer is not only in the mind of the deceased, but also in his heart.
