Discovering his memories have been manipulated, a security analyst must use clues hidden by himself to retrieve his real memories and expose his employer’s secret control over society.

What’s so special about the sinister secret that it must be exposed? There must be a 1,001+ plots about someone hiding a sinister secret. ?What’s so special about this one? ?What makes it?so sinister that he’s must not only expose it but stop the consequences and/or implications — NOW — or else?
