Antigone and Ismene return to Thebes to help their brothers but they then learn that their brothers were dead.
Antigone asked Ismene to help her bury her brother polyneices whom Creon refused to have buried. Ismene said that Creon will kill them if they bury poly nieces so Ismene decided not to do it. Antigone disagreed with Ismene, she belies that her brother deserves an honorable death no matter what he has done. So she decided to do it by himself.
Antigone went to bury her brother but is caught in the act by the sentry.
