Mr. Quaker, the American "Oyster King", resides with his unmarried daughter, Ossi, in a mansion attended by a large staff of servants. After hearing about a rival debutante's recent marriage to a
count, Ossi throws a tantrum. Also competitive, Mr. Quaker promises his daughter that he will find a suitable prince for her to marry. They engage a matchmaker, who locates Prince Nucki, an indebted down-on-his-luck royal, who hides his wealth from his poorer friends and his poverty from his wealthier associates. Hoping that the match would improve his financial situation, Prince Nucki agrees to send his friend Josef to meet Ossi on his behalf. When Josef arrives at the Quakers' residence, he accidentally provides Prince Nucki's calling card as his own. Ossi is not impressed with the visitor, but eager to be married and believing Josef to be the prince, she rushes them to a priest, where Ossi is immediately married to Josef, under Prince Nucki's name. A rushed but well-attended wedding reception follows the quick marriage. Both Mr. Quaker and Ossi are not fond of her new husband, but Josef thoroughly enjoys the rousing party, which features a "Foxtrot epidemic" that causes the whole house, including staff, to break into dance. Meanwhile, after a night of carousing with friends, the real Prince Nucki stumbles into a carriage that takes him to a meeting of the Multi-Millionaires' Daughters Association Against Dipsomania, of which Ossi is a member. There, the two meet and are immediately smitten. Not yet knowing each other's identities both are distraught, she believing herself to be recently married and he believing himself to be betrothed. Josef finds them together and, laughing, asks, "Do you know that you two are married to each other?" The happy couple celebrate with a second, much smaller reception, and in the end, Ossi, Prince Nucki, and Mr. Quaker are all pleased with the match. == Cast ==
