What is the plot of Antigone.

Polyneices and Eteocles, two brothers leading opposite sides in Thebes' civil war, have both been killed in battle. Creon, the new ruler of Thebes, has declared that Eteocles will be honored and Polyneices disgraced. The rebel brother's body will not be sanctified by holy rites, and will lay unburied to become the food of carrion animals. Antigone and Ismene are the sisters of the dead brothers, and they are now the last children of the ill-fated Oedipus. In the opening of the play, Antigone brings Ismene outside the city gates late at night for a secret meeting: Antigone wants to bury Polyneices' body, in defiance of Creon's edict. There will be grave repercussions for all characters.
