ACT I. Spain, 1600s.
At night, outside the Commendatore's palace, Leporello grumbles about his duties ("Notte e giorno faticar") as servant to Don Giovanni, a dissolute nobleman. Soon the masked Don appears, pursued by Donna Anna, the Commendatore's daughter, whom he has tried to seduce. When the Commendatore himself answers Anna's cries, he is killed in a duel by Giovanni, who escapes. Anna now returns with her fiancé, Don Ottavio. Finding her father dead, she makes Ottavio swear vengeance on the assassin ("Ma qual mai s'offre, o dei").
At dawn, Giovanni flirts with a high-strung traveler outside a tavern. She turns out to be Donna Elvira, a woman he once seduced in Burgos, who is on his trail. Giovanni escapes while Leporello distracts Elvira by reciting his master's long catalog of conquests ("Madamina, il catalogo è questo").
Peasants arrive, celebrating the nuptials of their friends Zerlina and Masetto. When Giovanni joins in, he pursues the bride, angering the groom, who is removed by Leporello. Alone with Zerlina, the Don applies his charm ("Là ci darem la mano"), but Elvira interrupts and protectively whisks the girl away. When Elvira returns to denounce him as a seducer ("Non ti fidar, o misera"), Giovanni is stymied further while greeting Anna, now in mourning, and Ottavio. Declaring Elvira mad, he leads her off. Anna, having recognized his voice, realizes Giovanni was her attacker.
Dressing for the wedding feast he has planned for the peasants, Giovanni exuberantly downs champagne ("Finch'han dal vino"). Outside the palace, Zerlina begs Masetto to forgive her apparent infidelity ("Presto, presto, pria ch'ei venga"). Masetto hides when the Don appears, emerging from the shadows as Giovanni corners Zerlina ("Riposate, vezzose ragazze!"). The three enter the palace together ("Venite pur avanti"). Elvira, Anna, and Ottavio are invited to the feast by Leporello. During the festivities, Leporello entices Masetto into the dance as Giovanni draws Zerlina out of the room. When the girl's cries for help put him on the spot, Giovanni tries to blame Leporello, but no one is convinced. Elvira ("Ecco il birbo che t'ha offesa"), Anna, and Ottavio unmask and confront Giovanni, who barely escapes Ottavio's drawn sword.
ACT II.
("Sola, sola, in buio loco") Under Elvira's balcony, Leporello exchanges cloaks with Giovanni to woo the lady in his master's stead. Leporello leads Elvira off, leaving the Don free to serenade Elvira's maid. When Masetto passes with a band of armed peasants bent on punishing Giovanni, the disguised rake gives them false directions, then beats up Masetto. Zerlina arrives and tenderly consoles her betrothed. In a passageway, Elvira and Leporello are surprised by Anna, Ottavio, Zerlina ("Mille torbidi pensieri"), and Masetto, who, mistaking servant for master, threaten Leporello. Frightened, he unmasks and escapes.
When Anna departs, Ottavio affirms his confidence in their love. Elvira, frustrated at her second betrayal by the Don, voices her rage. Leporello catches up with his master in a cemetery, where a voice warns Giovanni of his doom. This is the statue of the Commendatore, which the Don proposes Leporello invite to dinner ("O statua gentilissima"). When the servant reluctantly stammers an invitation, the statue accepts.
In her home, Anna, still in mourning, puts off Ottavio's offer of marriage until her father is avenged.
Leporello is serving Giovanni's dinner ("Già la mensa è preparata") when Elvira rushes in, begging the Don, whom she still loves, to reform ("L'ultima prova dell'amor mio"). But, he waves her out contemptuously. At the door, her screams announce the Commendatore's statue. Giovanni boldly refuses warnings to repent, even in the face of death ("Don Giovanni, a cenar teco"). Flames engulf his house, and the sinner is dragged to hell.
Among the castle ruins, the others plan their future and recite the moral: such is the fate of a wrongdoer.
