In New Arc City, rain is the eternal requiem and neon is the epitaph of the city. Here, memories can be purchased, edited and deleted like commodities. Ní Yīn is the most famous "memory colorist" in the industry. She can weave the most beautiful dreams for her clients and erase the most painful past. However, overnight, her own "canvas" was completely erased and turned into a "data ghost" with no past and no emotions.
Ling ভট্টাচার্য (Líng Bōttàchāng), a "mock detective" who stubbornly relies on intuition, pen and paper and logical reasoning in this digital age, took over what was officially defined as an "unsolvable" case. He does not believe in any data that can be tampered with, only in the traces of human nature that cannot be encoded.
When the artist who is best at constructing memories meets the detective who least trusts the virtual world, they will sneak into the most dangerous gray area of New Arc City - from the illegal memory black market to the skyscraper of the giant enterprise "Eternal Life Technology". What they want to recover is not only Niyin's stolen past, but also a shocking secret that can subvert the order of the entire city. In this game between fiction and reality, Ling ভট্টাচার্য must answer the ultimate question: When a person's entire memory is deprived of her, is she still her?
