Based on Aeschylus’ Oresteia.
This Restless House, Part One: Agamemnon's Return Script
Aeschylus' Oresteia opens with Agamemnon sacrificing his daughter to the gods; an act which sets in motion a bloody cycle of revenge and counter-revenge. When he in turn is killed at the hands of his wife Clytemnestra, their son Orestes takes up the mantle of avenging his father, continuing the bloodshed until peace is ultimately found in the rule of law.
