What is the conflict of antigone?

Creon has declared that the body of Polynices may not be given a proper burial because he led the forces that invaded Thebes, but Antigone wishes to give her brother a proper burial nevertheless.

Antigone is brought before Creon, and admits that she knew of Creon's law forbidding mourning for Polynices but chose to break it, claiming the superiority of divine over human law, and she defies Creon's cruelty with courage, passion and determination.
