In the "Xinqiong City" in 2049, the technology giant "Yongsheng Group" relied on its "Yihai" system to digitize human memories and realize the storage, retrieval and even editing of memories. Memory has become a commodity that can be quantified and traded. However, Gao Yuan, the group's top memory architect, died mysteriously in his apartment. The official conclusion was an "accident", but an unexplainable doubt hung over the case - the memory data of Gao Yuan's twenty-four hours before his death showed an absolute and technically "impossible" blank.
Private detective Ling Shuo, an "old antique" wandering in the gray area of the city, was commissioned by a mysterious anonymous client with a large sum of money to investigate the truth behind this "accident". At the same time, Yun Xi, the genius memory editor of the Yongsheng Group, as a colleague of Gao Yuan, also noticed something fishy about the incident. She took huge risks and became an "informant", guiding Ling Shuo step by step into the fog where data and reality intertwine.
When Ling Shuo's traditional criminal investigation logic collided with Yun Xi's cutting-edge memory technology, they discovered that Gao Yuan's death was far from an accident. A crazy plan about immortality of memory and uploading of consciousness, a "digital ghost" hidden deep in the torrent of data, is quietly surfacing. What they have to fight against is not only the powerful technological empire, but also the terrifying ambition that can subvert the definition of human existence. At the boundary between truth and falsehood, memory and forgetfulness, can they find the erased truth?
