"Memento: Prisoners of Time" is set in 2149 and tells the story of top hacker Lin Zhou (codenamed "Ghost") who became an experimental subject of the "Maze" organization's "Neural Memory Reconstruction Project" and woke up in the experimental center after his memory was tampered with. Driven by the memory warning of his mysterious partner Su Qing and his own instincts, he escaped from the cage and gradually revealed the truth: he was originally a core member of the "Freedom Alliance" and was arrested for exposing the "Maze" conspiracy; and the "Pharaoh" behind the organization was actually his most trusted mentor in the past, Professor Zhou.
