Disquieting is the word for Stefan Tamarov's first visit to New York City. As Minister of Economics and Foreign Trade for a Communist satellite country, Tamarov has no trouble with his official duties; it's the ""little"" things that bother him. His daughter Svezda is seeing an American reporter much too often, and his best friend Andreas Vrim, his country's UN delegate, has confided a few thoughts to Stefan that could be interpreted as treason.
The Devil Himself (Astaire) is a hard-bitten businessman with a group of somewhat bumbling yes-men on staff and a curvy assistant in the person of Elizabeth Montgomery (no Gwen Verdon, but fairly amusing, all the same). Together they use their best temptations in an attempt to thwart the honesty and decency of a young suburban couple (Aletter and Bulifant).
