In the future city, memories can be read and played back. "Memory Dream Weaver" Ling Su is a leader in the industry, specializing in sneaking into the memories of the deceased to explore the truth about death. When he accepted the commission and entered the depths of the memory of the technology giant Gu Yebai who was judged to have committed suicide, he discovered a "ghost" that should not exist - an afterimage of Gu Yebai with self-awareness. This afterimage struggles among the fragmented memory fragments, conveying the silent message "I did not commit suicide." Ling Su must piece together the cover-up truth of the murder before the memory world completely collapses, and at the same time fight against an unknown force that is trying to imprison him here forever.
