A megalomaniac has taken over the White House and proclaimed himself king.
In a last desperate offensive, Sulan and her friends set plans in motion for a risky cyberspace attack. To carry out their mission, they will design a new technology as dangerous as the enemy they face.
If they fail in their mission, their lives-and the fate of America-will be forfeit.
