The Duke of Mantua's court. Courtiers and the duke's hunchback jester Rigoletto amuse themselves playing nasty tricks and humiliating each other. The duke seduces and then abandons women to pass the time, mocking their husbands. He hasn't yet concluded his latest adventure with a young woman. Every Sunday, for three months, he's watched her in church. With the help of Rigoletto's stinging tongue he humiliates Countess Ceprano in front of her husband. When Rigoletto suggests the cuckolded Count Ceprano be executed, the mood suddenly turns against him. The courtiers demand revenge for Rigoletto's malice. Marullo reveals that the hunchback keeps a lover hidden at home. Count Monterone interrups the festivities, demanding vengeance for his daughter, who the duke and his men dishonoured. When Rigoletto mocks the despairing father, Monterone curses the duke and his jester. Rigoletto can't get Monterone's curse out of his mind. Out on the street Sparafucile, a professional assassin and his sister Maddalena offer their services. Rigoletto sees his mirror image in the murderer: Sparafucile kills with a dagger, he with humiliating words. Rigoletto bemoans his fate and tries to justify his actions to himself. He comes home, where his daughter Gilda is locked away from the outside world with her governess Giovanna. Gilda means everything to her him. She grew up in a convent and only came to live with him three months ago. Gilda longs for life and freedom. Rigoletto avoids answering her questions about her dead mother and his name. Before going out again he orders Giovanna to guard his daughter carefully. The duke bribes Giovanna and, disguised as a poor student, Gualtier Maldé, forces his way into the room, proclaiming his love for her, which Gilda immediately returns. The duke's sent away when Giovanna hears footsteps. Gilda falls into a reverie about her beloved's name. The courtiers break into the house to steal Rigoletto's supposed lover. Rigoletto, blindfolded, takes part in the crime in the mistaken belief that they're abducting Countess Ceprano. Too late, he realises that he helped steal his own daughter.
