The "Memory Palace" organization provides a revolutionary emotional service: through neural interaction technology, it guides the living to experience the precious memory fragments left by the deceased to comfort the grief. Anna is the agency's top "guide," known for her empathy and keen eye for the minutiae of memory.
Once, she was entrusted to guide a client to experience the memory of the legendary detective Gu Yuan. Gu Yuan died in a seemingly accidental warehouse fire, but his daughter firmly believed that there was something hidden behind it. When Anna delved into the memories of Gu Yuan's last few days, she not only found clues pointing to the murder, but also encountered an unprecedented horrifying situation - a key figure in the memory seemed to have broken through the dimensional wall of "memory", directly perceived the existence of Anna as a "bystander", and issued a fatal warning to her: "Get out, otherwise you will be like him."
Anna has since fallen into a deadly game that spans the dimensions of reality and memory. The killer is not only able to sense her prying eyes through his memories, but appears to be able to use this connection to influence reality. Anna must "cooperate" side by side with Gu Yuan's remaining memory fragments, looking for evidence in the intertwining of fiction and reality, while avoiding cold shots from the dark. She gradually understood that the last case investigated by Gu Yuan involved a huge dark organization that could manipulate memory and consciousness. And she herself has gone from a bystander to the next target on the murderer's list.
