In a future city where memories can be extracted, repaired and traded, Lin Mo is a lonely "memory fabricator". He is good at traveling through other people's broken mental landscapes to find the lost truth. One day, a woman named Chen Shuang came to the door with a strange commission - she wanted to retrieve the last words her brother said before he disappeared. When Lin Mo dived into Chen Shuang's deliberately blocked memory, he was shocked to find that he was not a bystander. On this isolated island made of memories, he not only has to face his client's past, but also a secret that he has long forgotten, which is enough to swallow the two of them completely.
