In the "Mirror City" where neon lights and rain curtains intertwine, memory becomes a commodity that can be read, tampered with and traded. Lin Mo, a top but infamous "memory weaver", makes a living by sneaking into other people's memories, but he is unable to retrieve his daughter's lost memories. A bizarre murder of a congressman involved him in a huge conspiracy. The only clue is a fragmented and chaotic memory fragment in the deceased's mind. When Lin Mo sneaked into this scarlet maze of memory, he found that he was not only pursuing the murderer, but also the cruel truth that could subvert the order of the entire Mirror City, as well as the opportunity for redemption that was closely connected with his dusty past.
