Shortly after Army lawyer Sean Drummond starts working for the Office of Special Projects, a CIA cell which handles the most dangerous threats, the White House Chief of Staff is found brutally murdered. A note left by the killer promises more victims - including the President. Teaming up with a beautiful colleague to try to stop the assassin, Sean begins the investigation. The killer is stalking the campaign trail, apparently driven by a $500 million bounty on the President's head. When a dramatic hostage rescue culminates in an intense shootout, Sean realizes law enforcement's horrible miscalculation and what to do about it.
