ACT I
Leporello, servant to the nobleman Don Giovanni, keeps watch outside the Commendatore’s home at night. Suddenly, the Commendatore’s daughter, Donna Anna, rushes out, struggling with the masked Giovanni and followed by her father. The Commendatore challenges Giovanni to a duel and is killed. Giovanni and Leporello escape. Anna asks her fiancé, Don Ottavio, to avenge her father’s death.

In the morning, Giovanni and Leporello encounter one of Giovanni’s former conquests, Donna Elvira, who is devastated by his betrayal. Leporello tells her she is neither the first nor the last woman to fall victim to Giovanni and shows her his catalogue with the name of every woman Giovanni has seduced.

Peasants celebrate the marriage of Masetto and Zerlina. Giovanni flirts with the bride, telling her she is destined for a better life. But Elvira urges Zerlina to flee her suitor. She also warns Anna, who is still unaware of the identity of her father’s murderer and has asked Giovanni for help in finding the man. Giovanni, for his part, insists that Elvira is mad, and Anna and Ottavio wonder what to believe. As Giovanni leaves, Anna suddenly recognizes his voice as that of the murderer. Devastated but determined, she once more asks Ottavio to avenge her. He wonders how to restore her peace of mind. Giovanni, who has invited the entire wedding party to his home, looks forward to an evening of drinking and dancing.
Outside Giovanni’s home, Zerlina asks Masetto to forgive her. Giovanni enters and leads them both inside. Anna, Elvira, and Ottavio appear masked and are invited in by Leporello. In the ballroom, Giovanni dances with Zerlina, then tries to drag her into the adjoining room. When she cries for help, Giovanni blames Leporello. Anna, Elvira, and Ottavio take off their masks and, along with Zerlina and Masetto, accuse Giovanni, who is momentarily surprised but manages to slip away.
