Ismene reveals to her sister, Antigone that Creon does not want their brother Polyneices to have a proper burial. This is due to the fact that he killed his own brother, Eteocles. This was all fought for the rights to the throne. They both managed to die in their duel and Creon, their uncle, took over and ordered Polyneices to not have a proper burial due to him being a traitor

Antigone doesn't take kindly to the decision made by Creon. Once she finds out she decides to give Polyneices the proper burial. Despite him being a traitor, he is her brother and she feels like he doesn't deserve the punishment he was given. She buries him and is caught in the act. Creon sends her to prison to live out the rest of her days for her disobedience

The End
Creon decides to change his mind and free her. When he arrives to her prison cell, it is too late and Antigone hanged herself. This causes Haemon to get very upset about the whole ordeal.
Haemon tries to kill Creon for causing his fiance's death. He could not bring himself to it so instead of killing Creon he killed himself. Creon then has practically no one and regrets his actions due to the result.
