A new dress plays a key role in the lives of four women who are not acquainted with each other. A daring strapless design, "Nude at Midnight," is unveiled in Paris, France to the delight of socialite Gogo Montaine, who wants to dazzle the Maharajah of Kim-Kepore, her escort that night. She charges its $900 cost to a former lover, Louis-Jean, who turns up later and refuses to pay. The Raj begins paying more attention to the gambling tables, so Gogo uses her dress and charms to get back into Louis-Jean's good graces.
