Second part of the {{tragedy}} trilogy ''Theatre/TheOresteia'' by Creator/{{Aeschylus}}.

Some time after [[Theatre/{{Agamemnon}} Agamemnonís murder]], his son Orestes and a friend, Pylades, arrive at his grave after a long exile. Soon, they both hide as Orestesí sister, Electra, arrives at the tomb with some slaves [[TitleDrop carrying libations]]. She sees two locks of hair in the tomb, left there by Orestes earlier, prompting him to come out of his hiding place and convince his sister of his identity.

She tells him of Aegisthus and Clytemnestraís plot to murder Agamemnon and, after a long rant that involves summoning the spirit of their father to help them, Orestes decides to avenge his father by murdering both his mother and her lover.

Orestes and Pylades pretend to be wandering travelers and knock on the door, calling on Aegisthus with news of Orestesí death. Clytemnestra, delighted, goes inside to call Aegisthus, only for him to die when he meets Orestes in private. When she finds out, he threatens to kill her too, in spite of her pleading and reminding him of the fact that she bore and raised him. Orestes has trouble deciding if he has to murder her too to avenge his father or not, but eventually decides the cause is just and does it. Then he wraps both corpses on Agamemnonís cloak.

Sadly for Orestes, the cycle of violence doesnít end there. Anyone in ancient Greece who slays a family member has broken a serious moral law, and becomes the rightful prey of the Erinyes or Eumenides ("Kindly Ones,") aka the Furies, incarnations of vengeance whom even the gods cannot control. The story continues in ''Theatre/{{Eumenides}}''...
