In a make-believe, mittleuropean kingdom, a vivacious but dim country girl sings in a beer garden for her rent money. Meanwhile, the king is facing bankruptcy for his little nation, unless he marries a rich but undesirable queen of another comic opera principality. Eventually he takes in the struggling young singer, and they fall in love, despite possible ruin.
