Resentful after an ugly divorce from her unfaithful husband, Judith McGuire moves to Los Angeles. Adrift and detached, she spends her days and nights wandering through her new city, cynically remarking on the hypocrisy, vanity and brutality of the modern world and humanity's alienation from themselves and each other.

In this musical-comedy, Dean Martin plays an American hotel mogul who becomes smitten with a young Italian woman (Anna Maria Alberghetti) when buying a hotel in Rome. To marry this gal, he has to get her three older sisters married off.
