The Office of Special Project is a CIA cell that handles the most dangerous threats. When the White House chief of Staff is found brutally murdered alongside a note promising more murders - and a President who will be "history" in three days - Sean Drummond teams with a beautiful colleague, Jennie Margold, to try to stop the assassin. As the killer stalks the campaign trail, apparently driven by a $500 million bounty on the President's head, all arrows point to a member of the White House security detail who has mysteriously gone missing. But as time trickles down to precious minutes, Sean realizes law enforcement's horrible miscalculation - and what must be done to side step disaster.
