Kate Capshaw plays a schoolteacher and suburban housewife who happens to be an ex-spy. Nobody knows of Capshaw's previous espionage activities, least of all her somewhat obtuse husband Cliff De Young. When Capshaw's ex-lover Jeroen Krabbe, an intimate of Castro, lands in a Cuban prison, she is swept back into the spy business, leaving her nonplussed hubby in the dust.
