George Beban plays feisty Italian immigrant Luigi Riccardo, the eternal thorn in the side of New York political boss Regan (H.B. Carpenter). Fed up with Riccardo's interference in his graft-grabbing, Regan pulls a few strings and arranges for Riccardo and his family to be shipped back to Europe.

Rejected by the army because of his petite size, French dress designer Andre Leriche conceives the idea of designing a gown that will aid his country. His employer, Madame Felice, sells the gown to Mrs. Mortimer Reyton, a middle-aged woman who is gradually losing the love of her husband. The gown so transforms her that, in honor of their wedding anniversary, Reyton buys three ambulances for France. Mrs. Reyton then sends the gown to her cousin Natalie. The garment so inspires Englishman Neil Cunningham that, to win Natalie's love, he returns home to enlist. In France, Neil proves himself a hero and, while leading an attack on a German stronghold, saves Andre's father, the mayor of the town, from death. Thus, the gown made a reality of Andre's dream to serve his country.
