The play begins with the introduction of Electra, the daughter of Clytemnestra and the late Agamemnon. Several years after Agamemnon's death suitors began requesting Electra's hand in marriage. Out of fear that Electra's child might seek revenge, Clytemnestra and Aegisthus married her off to a peasant of Mycenae. The peasant is kind to her and has respected her family name and her virginity. In return for his kindness, Electra helps her husband with the household chores. Despite her appreciation for her husband's kindness, Electra resents being cast out of her house and laments to the Chorus about her struggles with her drastic change in social status. Upon Agamemnon's murder Clytemnestra and Aegisthus put Orestes, the other child of Clytemnestra and Agamemnon, under the care of the king of Phocis, where he became friends with the king's son, Pylades. Now grown, Orestes and Pylades travel to Electra and her husband's house. Orestes keeps his identity hidden from Electra, claiming to be messengers of Orestes. He uses his anonymity to determine Electra's loyalty to him and Agamemnon before he reveals his plans for revenge. After some time it is clear that Electra is passionate about avenging the death of their father. At this point the aged servant who brought Orestes to Phocis years before enters the play. He recognizes Orestes because of the scar on his brow and the siblings are reunited. They begin to plot how they will murder both Aegisthus and Clytemnestra. The aged servant explains that Aegisthus is currently in his stables, preparing to sacrifice oxen for a feast. Orestes goes to confront Aegisthus while Electra sends the aged servant to tell Clytemnestra that she had a son ten days ago, knowing this will bring Clytemnestra to her house. A messenger arrives and describes Orestes' successful murder of Aegisthus. Orestes and Pylades return bearing Aegisthus' body. As Clytemnestra approaches, Orestes begins to waver on his decision to murder their mother. Electra convinces Orestes that he must fulfill his duty to Agamemnon and murder their mother. When Clytemnestra arrives, Orestes and Electra lure her into the house, where they thrust a sword into her throat. The two leave the house, filled with grief and guilt. As they lament, Clytemnestra's deified brothers, Castor and Pollux, appear. They tell Electra and Orestes that their mother received just punishment but their matricide was still a shameful act, and they instruct the siblings on what they must do to atone and purge their souls.
