Act I: Leporello, servant
to Don Giovanni, tells of the difficulties he must endure as the servant
to the immoral nobleman. Donna Anna appears, struggling with Don Giovanni.
Her father, the Commander, hears her cries and appears on the scene.
A sword fight ensues, Giovanni kills the Commander and escapes with
Leporello. Donna Anna, who has left to get help, returns with her fiancé,
Ottavio, to find her father murdered.
Donna Elvira appears searching for Don Giovanni, who has abandoned
her. Leporello tries to discourage her by listing his master's numerous
conquests. Masetto and Zerlina enter singing and dancing in anticipation
of their approaching wedding. Giovanni is instantly attracted to Zerlina
and orders Leporello to entertain Masetto so the Don may privately invite
Zerlina to his home. Donna Elvira interrupts and takes Zerlina away.
Donna Anna recognizes Giovanni as the man who attacked her and orders
Ottavio to take revenge.
Elvira, Anna, and Ottavio plot against Giovanni and plan to trap him
at a ball that evening. During the ball, Giovanni lures Zerlina into
a private room. She screams in protest. Elvira, Anna, and Ottavio confront
Giovanni, but he escapes once again.
Act II: Giovanni convinces
Leporello to "run interference" for him. Disguised as Giovanni,
Leporello lures Elvira from her house leaving Giovanni free to woo Elvira's
beautiful maid. Giovanni (dressed as Leporello) manages to disband the
posse organized by Masetto and wounds Masetto in the process. Anna,
Ottavio, Zerlina, and Masetto come upon Elvira and Leporello. Leporello
takes off his disguise and flees from the garden. Ottavio surmises that
Giovanni killed the Commander. Elvira admits she still loves Giovanni
despite everything. Anna affirms her love for Ottavio, but confesses
she cannot give herself to him until her father's death is avenged.
While hiding in the cemetery, Leporello and Giovanni discover the Commander's
tomb and jokingly ask his statue to dinner. To their surprise, the statue
accepts. Later that evening, the statue arrives and summons Giovanni
to hell, leaving the others to reflect on the result of Giovanni's immorality.
