In the future city "Xinhai" where memories can be extracted, stored and traded, Lin Mo, a top memory appraiser, makes a living by repairing other people's broken memories, but he is unable to piece together his own past. His only clue was a lonely lighthouse that kept recurring in his mind. A seemingly ordinary commission brought an unreadable "blank" memory chip, which unexpectedly unlocked a corner of his dusty past. In order to pursue the truth, Lin Mo embarked on a dangerous journey. In the intertwined lies and truth, he had to face an ultimate question: when memories can be tampered with and forged, how should we define "self"? This is not only a retrieval of the past, but also a battle to reposition the island of one's existence in a sea of oblivion.
