In the near future where memories can be read and reviewed, top memory reviewer Lin Mo is ordered to investigate a bizarre secret room murder case. The only "eyewitness" is the last memory extracted before the death of the murdered genius scientist Su Yao. However, this seemingly clear memory is full of unexplainable distortions and fractures, and the murderer's face is always shrouded in fog. When Lin Mo dived into the depths of Su Yao's broken consciousness time and time again, he not only discovered that the truth of the case was far beyond imagination, but was also shocked to realize that a past he had forgotten was closely connected with the abyss of memory. What he is looking for may not only be the murderer, but also his lost self.
