The Buccaneers.

Because of their "new money" background, four American girls have difficulty breaking into the upper-crust society of New York. Laura Testvalley, the governess of one of the girls, suggests a London season and thus the young women set sail for England and the unsuspecting English aristocracy. In England, all the girls soon find eligible husbands and the youngest girl, Nan, seems to land the best husband of them all: the handsome and very wealthy Julius, Duke of Trevennick. The girls soon discover that English upper-class men are not at all what they expected and hoped for.
