Antigone picks up where Oedipus at Colonus leaves off. Oedipus has just passed away in Colonus, and Antigone and her sister decide to return to Thebes with the intention of helping their brothers, Eteocles and Polyneices, avoid a prophecy that predicts they will kill each other in a battle for the throne of Thebes.
Upon her arrival in Thebes, Antigone learns that both of her brothers are dead. Eteocles has been given a proper burial, but Creon, Antigone's uncle who has inherited the throne, has issued a royal edict banning the burial of Polyneices, who he believes was a traitor. Antigone defies the law, buries her brother, and is caught. When Creon locks her away in prison, she kills herself.
Meanwhile, not realizing Antigone has taken her own life, the blind prophet Teiresias, Creon's son and Antigone's fiancé Haemon, and the Chorus plead with Creon to release her. Creon finally relents, but in an instance of too-late-timing, finds her dead in her jail cell. Out of despair, Haemon and Creon’s wife have by now also killed themselves, and Creon is left in distress and sorrow.
