Don Pasquale, an elderly, miserly bachelor, grows impatient with his nephew Ernesto's romantic entanglements and threatens to disinherit him unless he marries a woman of Don Pasquale's choosing. The scheming Dr. Malatesta convinces Don Pasquale that he himself should marry, presenting the supposedly demure and obedient Norina—who is actually Ernesto's beloved in disguise—as a suitable bride. Don Pasquale eagerly agrees and marries her immediately. Once wed, Norina transforms into a vain, extravagant spendthrift, running up enormous debts and humiliating her new husband at every turn. Desperate and miserable, Don Pasquale is eventually persuaded to annul the marriage and consent to Ernesto and Norina's union, restoring peace and allowing the young lovers their happiness while Don Pasquale retreats to his solitary existence, wiser if not happier.
