In the future city "Xinhai" where memories can be extracted, traded and even erased, Lin Zhou is a "memory scavenger". He wanders around the edges of the city, making a living by searching for and selling abandoned memory fragments, but deep down he is tortured by a blank memory about his sister. One day, a mysterious woman in red commissioned him to find a seemingly worthless childhood memory, and he paid a shocking price for it. This weird business dragged Lin Zhou into a huge whirlpool composed of technology giants, the black market of memory and the concealed past. He discovered that that forgotten memory was not only the key to unlocking the mystery of his life experience, but also involved a dark truth that could subvert the entire Xinhai City.
