In the future city "New Green City" where memories can be extracted, stored and restored, Ling Chen is a top but lonely memory restorer. He regards memory as a sacred object and his studio as an island away from the hustle and bustle, calmly repairing the broken past of others. One day, a mysterious customer brought a memory crystal that could not be analyzed and even "resisted" reading. In the crystal, a woman named "Yi" appears repeatedly, but this person is not found in any official records. This dangerous memory, like a stubborn stone thrown into still water, completely broke Ling Chen's order. He was forced to leave the island and embark on a journey to pursue the truth, but found that he was stepping into a huge whirlpool that could subvert the memory structure of the entire city, and his own forgotten past was also closely connected with this ghostly woman.
