When Moses encounters the voice of God, he learns that only he has the power to fight the Pharaoh of Egypt and free the Hebrew slaves. With the help of his brother Aaron, he begs the Pharaoh to free the slaves, but he refuses many times. When God kills the Pharaoh's son and many of his people, he finally surrenders. As Moses and the slaves approach the Red Sea, they learn that the Pharoah has changed his mind and has sent his men to bring them back. But with the help of God, Moses is able to free them once and for all.
