Antigone Summary – Shmoop

Antigone picks up in the same (uber-dismal) place that 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.
