During the long journey that brought him home victorious in the Trojan War, Agamemnon fell in love with one of his captives, Cassander, daughter of Priam, with whom he had children. The reception in Argos, more than ten years later, was icy. Annoyed by the double indelicacy of her husband, Clytemnestra, his wife who had meanwhile become the mistress of Aegisthus, killed him with the help of her lover. Aegisthus then became the regent and ensured the prosperity of the city alongside his mistress, the widowed queen. But Electra, one of the daughters of Agamemnon, has always foreseen the murder and adultery of her mother. Solitary, wild, she lives in the royal palace awaiting the return of Orestes, her brother who has taken refuge since childhood with an uncle, in order to take revenge. Electra can begin, the crimes of the Atreides family continue quietly, as planned.
