In the future city "New Kyoto" where memories can be extracted, weaved and traded, Lin Mo, the top memory weaver, can repair any broken memory, but he cannot piece together his own past. His only clue was a silver butterfly hairpin and a vague girl's face that flashed repeatedly in his mind. In order to find himself, he accepted a dangerous commission from the mysterious client "Mr. Crow", sneaked into the core of the giant company "Eternal Life Technology", and stole a blocked memory. However, as he stepped closer to the truth, he discovered that his forgetfulness was not an accident, but the key to a huge conspiracy that could subvert the entire city's order. He must retrieve the buried love and betrayal in the maze of memory.
