In Xinhai City in the 22nd century, memories can be extracted, repaired and even traded. Lin Mo, a top but closed-minded "memory restorer", makes a living by sneaking into other people's broken memories. He is both a healer and a spy. A mysterious commission from technology giant Gu Yuanshan involved him in a huge conspiracy. Gu Yuanshan asked Lin Mo to restore the memory of his late daughter Gu Nian and find a lost "Creation Formula". However, when Lin Mo dived into Gu Nian's sea of memories full of contradictions and fears, the truth he discovered was far more dangerous than a formula. This is not only a second autopsy of the deceased, but also a cruel trial of his own dusty past. He must ferry a girl's soul and himself through the turbulent flow of memories.
