In a future world where memories can be edited, transplanted or even forged, neural memory engineer Lin Su finds himself trapped in a huge conspiracy about "reality". He has the extraordinary ability to repair, reshape and even create memories, but he cannot bridge a gap in his childhood. When he tried to explore the forgotten past through technological means, he accidentally revealed a secret project called "Odyssey", which aimed to control human consciousness and even rewrite history through memory reconstruction. Lin Su's true love, An Ning, an artist who had completely lost his memory due to an accident, seems to be inextricably linked to this project. The recurring mysterious symbols in her paintings and the fragments of memories she occasionally reveals that do not belong to her all point to a carefully woven lie. In the labyrinth of memories that are difficult to distinguish between true and false, Lin Su must race against time, not only to solve the mystery of his and An Ning's self-identity, but also to prevent a crisis that may subvert the nature of human existence. The truth he is pursuing may be more cruel than he imagined, because when memory is no longer private property and when the definition of "I" can be tampered with at will, how will human beings define themselves?
