The play begins with a soliloquy that outlines the basic plot and events that have led up to this point from Electra, who stands next to a sleeping Orestes. Shortly after, Helen comes out of the palace under the pretext that she wishes to make an offering at her sister Clytemnestra's grave. After Helen leaves, a chorus of Argive women enters to help advance the plot. Then Orestes, still maddened by the Furies, awakes. Menelaus arrives at the palace, and he and Orestes discuss the murder and the resulting madness. Tyndareus, Orestes' grandfather and Menelaus' father-in-law comes onto the scene and roundly chastises Orestes, leading to a conversation with the three men on the role of humans in dispensing divine justice and natural law. As Tyndareus leaves, he warns Menelaus that he will need the old man as an ally. Orestes, in
supplication before Menelaus, hopes to gain the compassion that Tyndareus would not grant in an attempt to get him to speak before the assembly of Argive men. However, Menelaus ultimately shuns his nephew, choosing not to compromise his tenuous power among the Greeks, who blame him and his wife for the Trojan War. Pylades, Orestes' life-long friend and his accomplice in Clytemnestra's murder, arrives after Menelaus has exited. He and Orestes begin to formulate a plan, in the process indicting partisan politics and leaders who manipulate the masses for results contrary to the best interest of the state. Orestes and Pylades then exit so that they may state their case before the town assembly in an effort to save Orestes and Electra from execution, which proves unsuccessful. The off-stage assembly-scene (reported by a messenger) is immensely detailed, containing speeches from four different speakers as well as Orestes himself. Their execution certain, Orestes, Electra, and Pylades formulate a plan of revenge against Menelaus for turning his back on them. To inflict the greatest suffering, they plan to kill Helen and hold her daughter, Hermione, hostage in order to escape harm. However, when they go to kill Helen, she vanishes. In attempting to execute their plan, a Phrygian slave of Helen's escapes the palace. Orestes asks the slave why he should spare his life, and the slave supplicates himself before Orestes. Orestes is won over by the Phrygian's argument that, like free men, slaves prefer the light of day to death. Menelaus then enters leading to a standoff between him and Orestes, Electra, and Pylades, who have successfully captured Hermione. Just as more bloodshed is to occur, Apollo arrives on stage
deus ex machina. He sets everything back in order, explaining that he has rescued Helen to place her among the stars, and that Menelaus must go back to Sparta. He tells Orestes to go to Athens to the
Areopagus, the Athenian court, in order to stand judgment, where he will later be acquitted. Also, Orestes is to marry Hermione, while Pylades will marry Electra. Finally, Apollo tells the mortals to go and rejoice in Peace, most honored and favored of the gods. == Themes ==
