Deep in the heart of Russia, a group of casually dressed young men are learning a different kind of lesson. The undergraduates sprawled around a game board aren’t chilling out on campus: the young KGB agents attending the Charm School are brushing up on their American. When a young tourist goes to the aid of a stranger on a dark Russian road, he is astonished to find a fellow American on the run. The man has been missing for over a decade, plucked from the jungles of Vietnam to become an unwilling tutor at the institution. Now his former students are poised to strike at the heart of America.
