When he accidentally takes possession of a top-secret invisibility potion while en route to his wedding, government bureaucrat Sam Cooper finds himself engulfed in a madcap free-for-all as Russians and other bad guys try to get the substance. To elude the Reds, his own State Department bosses and his livid fiancée, Cooper takes the vanishing juice himself—which only makes matters worse.

For the first time in history a woman is appointed to the U.S. Supreme Court, where she becomes a friendly rival to a liberal associate.

This film tells the true-life story of Yuri Nosenko, a top Soviet KGB agent who defected to the West at the height of the Cold War in 1962.
