Ling Yun, the genius memory architect, woke up from a coma and found himself imprisoned in the "Prism", a super prison designed by himself and claimed to be unbreakable. He was charged with high treason, but lost all critical memories. In this mirrored city of cold data and distorted reflections, every inch of space is under surveillance. Under the strict supervision of his former colleague and now the warden, he must rely on the remaining memory fragments and the whispers of a mysterious prisoner to unravel the maze he set up and find out the truth. Otherwise, he will not only lose his life, but also become a forgotten ghost among his creations.
