Scene 1 – Street outside the Commendatore’s brownstone
Leporello, Don Giovanni’s servant, complains of his lot in life. He’s keeping watch while Don Giovanni breaks into the room of the Commendatore’s daughter, Donna Anna. When the two appear, Giovanni is masked, but Donna Anna is holding onto his arm. Something has transpired, and she insists on knowing his true identity. She cries for help. The Commendatore appears and forces Giovanni to a duel. Giovanni slays the Commendatore and escapes with Leporello. Anna returns with her fiancé, Don Ottavio, and is horrified to see her father lying dead in a pool of his own blood. She makes Ottavio swear vengeance against the unknown murderer.
Scene 2 – Outside a café on the upper west side of the city
Giovanni and Leporello arrive and hear a woman (Donna Elvira) singing of having been abandoned by her lover. Giovanni starts to flirt with her, but he is the man she is seeking. He shoves Leporello forward, ordering him to tell Elvira the truth, and then hurries away.
Leporello tells Elvira that Don Giovanni is not worth it. His conquests include 640 women in Italy, 231 in Germany, 100 in France, 91 in Turkey, but in Spain, 1,003. When she leaves, a marriage party with Masetto and Zerlina enters. Don Giovanni and Leporello arrive soon after. Giovanni is immediately attracted to Zerlina, and he attempts to remove the jealous Masetto by offering to host a wedding celebration at his nightclub. On realizing that Giovanni means to remain behind with Zerlina, Masetto becomes angry. Don Giovanni and Zerlina are soon alone, and he immediately begins trying to seduce her.
Elvira arrives and stops Giovanni from assaulting Zerlina. Ottavio and Anna enter, arguing about whether to take matters of the death of her father into their own hands. Ottavio and Anna see their friend Giovanni. Anna, unaware that she is speaking to her attacker, pleads for Giovanni’s help. Giovanni, relieved that he is unrecognized, readily promises it and asks who has disturbed her peace. Before she can answer, Elvira returns and tells Anna and Ottavio that Giovanni is a liar. Giovanni tries to convince Ottavio and Anna that Elvira is insane. As Giovanni leaves, Anna suddenly recognizes him as her father’s murderer and the man who sexually assaulted her. Ottavio, not convinced, resolves to keep an eye on his friend.
Leporello informs Giovanni that all the guests of Zerlina and Masetto’s wedding are in Giovanni’s house and that he distracted Masetto from his jealousy, but that Zerlina, returning with Elvira, made a scene and spoiled everything. However, Don Giovanni remains cheerful and tells Leporello to organize a party and invite every girl he can find.
Zerlina follows the jealous Masetto and tries to pacify him, but just as she manages to persuade him of her innocence, Don Giovanni’s voice from offstage startles and frightens her. Masetto hides, resolving to see for himself what Zerlina will do when Giovanni arrives. Zerlina tries to hide from Don Giovanni, but he finds her and attempts to continue the seduction, until he stumbles upon Masetto’s hiding place. Confused but quickly recovering, Giovanni reproaches Masetto for leaving Zerlina alone and returns her temporarily to him. Giovanni then leads both to his nightclub. Leporello invites three masked guests to the party: the disguised Ottavio, Anna, and Elvira. Ottavio and Anna pray for protection, Elvira for vengeance.
Scene 3 – Giovanni’s nightclub
As the party proceeds, Leporello distracts Masetto by dancing with him, while Don Giovanni leads Zerlina offstage to a private room. When Zerlina screams for help, Don Giovanni tries to fool the onlookers by dragging Leporello into the room and threatening to kill him for assaulting Zerlina. But Ottavio threatens Giovanni with a gun, and the three guests unmask and declare that they know all. But despite being denounced on all sides, Don Giovanni escapes—for the moment.
Scene 1 – A dark alley
Leporello threatens to leave Giovanni, but his boss calms him with a peace offering of money. Wanting to seduce Elvira’s maid, Giovanni persuades Leporello to exchange cloak and hat with him. Elvira comes to her window. Seeing an opportunity for a game, Giovanni hides and sends Leporello out in the open dressed as Giovanni. From his hiding place, Giovanni sings a promise of repentance, expressing a desire to return to her, while Leporello poses as Giovanni and tries to keep from laughing. Elvira is convinced and descends to the street. Leporello, continuing to pose as Giovanni, leads her away to keep her occupied while Giovanni serenades her maid. Before Giovanni can complete his attempt to seduce the maid, Masetto and his friends arrive, searching for Giovanni and intending to kill him. Giovanni (dressed as Leporello) convinces the men that he also hates Giovanni and joins the hunt. After frightening Masetto’s friends, Giovanni takes Masetto’s weapons away, beats him up, and runs off, laughing. Zerlina arrives and consoles the bruised and battered Masetto.
Scene 2 – Later in the same dark alley
Leporello abandons Elvira. As he tries to escape, Ottavio arrives with Anna, consoling her in her grief. Just as Leporello is about to slip through the door, which he has difficulty finding, Zerlina and Masetto open it and, seeing him dressed as Giovanni, catch him before he can escape. When Anna and Ottavio notice what is going on, all move to surround Leporello, threatening him with death. Elvira tries to protect the man whom she thinks is Giovanni, claiming that he is her husband and begging for pity. The other four are resolved to punish the traitor, but Leporello removes his cloak to reveal his identity. He begs everyone’s forgiveness and, seeing an opportunity, runs off. Given the circumstances, Ottavio is convinced that Giovanni was the murderer of Donna Anna’s father (the deceased Commendatore) and swears revenge. Elvira is still furious at Giovanni for betraying her, but she finds her love for Giovanni compels her to try to save him from himself.
Scene 3 – A graveyard with the statue of the Commendatore
Leporello tells Don Giovanni of his brush with danger, and Giovanni taunts him, saying that he took advantage of his disguise as Leporello by trying to seduce one of Leporello’s girlfriends. The voice of the statue warns Giovanni that his laughter will not last beyond sunrise. At the command of his master, Leporello reads the inscription on the statue’s base: “I’m waiting for revenge against my murderer.” The servant trembles, but the unabashed Giovanni orders him to invite the statue to dinner, threatening to kill him if he does not. Leporello makes several attempts to invite the statue to dinner but, for fear, cannot complete the task. It falls upon Don Giovanni himself to complete the invitation, thereby sealing his own doom. Much to his surprise, the statue nods its head and responds affirmatively.
Scene 4 – Later in the same graveyard
Ottavio pressures Anna to marry him, but she thinks it inappropriate so soon after her father’s death. He accuses her of being cruel, and she assures him that she loves him and is faithful.
Scene 5 – Don Giovanni’s nightclub
Giovanni demands that Leporello and his waiters set up a dinner and musical entertainment. Elvira appears, saying that she no longer feels resentment for Giovanni, and she begs him to change his life. Giovanni taunts her and then turns away, praising wine and women as the “essence and glory of humankind.” Hurt and angered, Elvira gives up and leaves. A moment later, her scream is heard. Giovanni orders Leporello to see what has upset her; upon looking, Leporello also cries out, and runs back into the room, stammering that the statue has appeared as promised. An ominous knocking sounds at the door. Leporello, paralyzed by fear, cannot answer it, so Giovanni opens it himself, revealing the statue of the Commendatore. The Commendatore offers a last chance to repent, but Giovanni adamantly refuses. The statue grabs Giovanni’s hand and drains the life out of him. Hellfire and a chorus of demons are heard, and Don Giovanni disappears.
Donna Anna, Don Ottavio, Donna Elvira, Zerlina, and Masetto arrive, searching for Giovanni. They find instead Leporello hiding under the table, shaken by the supernatural horror he has witnessed. Now that Giovanni is dead, Donna Anna, Don Ottavio, Donna Elvira, Zerlina, Masetto, and Leporello decide what to do next.
