In the future city "Xijing", memories can be extracted and traded. Lin Chen, the top "memory weaver", can repair and reorganize broken memory fragments. He works for money, and also to find the incomplete dream about a glass bird that recurs in his mind. One day, the mysterious woman Su Wan brought an impossible commission: to retrieve a specific memory that she sold ten years ago. This transaction dragged Lin Chen into a huge whirlpool. He discovered that that forgotten memory was not only related to Su Wan's life and death, but also closely connected with his own lost past and the darkest secrets beneath the city's glamorous appearance.
