In a future city where memories can be bought, sold and implanted, "Zero", a social creature who follows the rules, leads a life as precise and numb as data. An unexpected system "failure" caused him to begin to receive memory fragments that were not his own - the obsession, skills and fears of a missing detective. In order to find "self", Zero is forced to embark on a dangerous journey to pursue the truth. In the torn apart of two souls, he not only has to fight against the giant corporations that sell memories, but also has to face an ultimate question: When memory is no longer reliable, who am I?
