Don Juan by Moliére is a comedic play about the fictitious Don Juan, a notoriously atheistic and adulterous individual. Moliére's play takes place over the course of Don Juan's final two days and illustrates the total depravity of his life.

The story starts out with Don Juan's servant, Sganarelle, speaking with the servant of Donna Elvire, Don Juan's new wife. Sganarelle claims that Don Juan is a womanizer and can't settle down with a single woman to save his life. Soon thereafter, Don Juan enters and talks with Sganarelle about the newest object of his affections, a young woman who is not his new wife, proving Sganarelle's claims. Don Juan and Donna Elvire argue about Juan's whereabouts, enraging Elvire. Later, in the countryside, Don Juan convinces another woman, Charlotte, to marry him but is interrupted by yet another of his "betrotheds," Mathurine. He convinces both of them that it has all been a misunderstanding, and upon hearing that he is being pursued by twelve men on horseback, Juan and Sganarelle flee the scene.

In the woods, having fled from their pursuers, Don Juan and Sganarelle save a man from attack by a robber, who happens to be Donna Elvire's brother, Don Carlos. Elvire's other brother, Don Alfonso, enters and, upon recognizing Don Juan, attempts to kill him, for Carlos and Alfonso have been seeking revenge on Juan for his treatment of their sister. Carlos convinces Alfonso to wait, because Juan saved his life just moments before. Don Juan is able to leave the scene and return home.

At Don Juan's home, he is visited by several people: one is a creditor who is turned away rather easily, and one is Juan's own father, who tells Juan of his disappointment in and contempt for his son and the life he has chosen. Finally, Donna Elvire comes to lovingly persuade Juan to change his ways, lest he burn in hell for his actions, but her entreaties have no effect.

Don Juan later finds his father in the country and tells him that he has repented, but he secretly reveals that he only said that to appease his father. After confronting Don Carlos, Don Juan is swallowed by the earth and the fires of hell as he is dragged to eternal damnation for his crimes, ending his terrible legacy.
