Twelve strangers wake up in a run-down hotel with no memory of who they are or how they got there. A mysterious computer avatar informs them that they have all committed a horrible crime, and their punishment is living out the rest of their lives in the hotel. Only one of them will be allowed out, and that is only if they murder everyone else in the building first. Who is behind this kidnapping? Why can't the twelve strangers remember anything? And who will be willing to kill in order to be set free?
