An "innocent" bourgeois American couple, a doctor and his wife, get mixed up, while vacationing abroad, in "foreign" intrigue, with a (pro-US) Latin American dictator. And not only are they "innocent", but so is the American oil company executive (who, however, lets them know that he's an "unofficial" US ambassador). (All the Americans here are innocent. Only the Americans here are innocent.) But still it's not as bad as it sounds. It's like a Hitchcock movie, but without Hitchcock, less stylish, more serious.
