Answer:
Antigone and Ismene are sisters. The story centres around the undignified way in which their brother's body has been left (at the time the women of the family would prepare the body for burial), and the king has made it illegal to bury him. Antigone believes that justice would be served if she defies the law, risking death if she is caught, and buries her brother. Ismene abides by the law and does not help to bury the body.
