A President going slowly but surely insane - is that any way to run a country? Maybe not, but what would America and its leaders do if it happened? President Terence Emerson Grantham has it all -- power, charisma, and boundless popularity. And he's loyally and expertly served by Chief of Staff John McMasters - "Mr. Superfixer" - the most skillful, canny operative a President ever had. That's why McMasters and the rest of the nation are so stymied when the President gets odd, then weird, then downright deranged - and the country realizes that you can't impeach someone for being nuts. The powers that be try every political maneuver they can think of to get rid of the loopy chief executive, including to invoke the 25th Amendment to the Constitution - an involved process, but it might be the nation's only hope as Grantham's behavior progresses from silly to dangerous. But the President keeps outwitting them all. Finally a group of powerful men decide they must assassinate Grantham - and McMasters may join them. Just what will it take to remove an insane head of state - and at what cost?
