Moses, a Hebrew baby, is found amongst the bulrushes by the Pharaoh's daughter. Aaron, Moses stepbrother, resents Moses who grows up the more sensible and likeable of the two and who was always the favourite of their grandfather, the Pharaoh. When Moses is given the task of leading his people to the promised land by his God, he creates havoc and brings plagues on the Pharaoh and the Egyptians who try to thwart his progress.

Aaron learns to love and respect Moses and his God. Under God's guidance and with Aaron's help, Moses delivers the Hebrew people from Egypt and away from the pursuing soldiers, across the Red Sea.
