In the future city "Veridia" where memories can be extracted, traded, and even erased, Lin Mo, a top memory restorer, makes a living by repairing other people's broken memories, but is unaware of his own past. One day, a mysterious woman Eve brought an unanalyzable memory fragment and asked him to retrieve a memory that "never happened". This seemingly absurd commission dragged Lin Mo into a huge whirlpool. He discovered that this fragment was inextricably linked to his forgotten past and the "Island of Memory" that only existed in legend and was related to the ultimate secret of human memory. On the way to pursue the truth, he not only has to fight against the "scavengers" that monitor his memory, but he also has to face his deepest fears and lies.
