Her younger sister, weighing in the neighborhood of 300 pounds and who is also the family favorite, is sought by the eligible men of the court.

Their romance is interrupted when a cable calls the princess and her bodyguard back to Morovenia. Arriving at home thinner than when she left, Kalora is thrown into a dungeon. When Alexander, whose millions are no less powerful in Morovenia than in America, arrives, he convinces her father of his love for Kalora, marries the princess, thus opening the way to the altar for the second daughter, and all are happy.
