Antigone goes to her sister Ismene to ask for her help in burying their brother Polyneices, whom Creon prohibits the burial of, unlike their other brother Eteocles who Creon has allowed a proper burial. Ismene does not want to help because she is afraid of what Creon will do if they break the law.
Creon addresses the choragus and tries to gain their trust, he also tells them about the new law he has enforced. A sentry arrives and tells Creon that Polyneices has been buried, but he does not know who has done it.
The sentry returns leading Antigone. He tells Creon that it was Antigone who buried Polyneices, Antigone does not try to deny his claim. Creon demands Ismene's presence because she knew what Antigone was doing but did not stop her or tell Creon. Creon decides to kill both Antigone and Ismene
