The first part of the film is given over to the Egyptian Genesis. The Egyptians had many gods and goddesses and creation myths. Ra brings these myths together in a single version and concentrates on the story of Osiris and Isis and their battle with their evil brother Set. Part two shows the intertwining of the world of the gods with that of the Divine Pharaoh, whom the ancient Egyptians believed to be the son of the Sun God Ra. The life of the Divine Pharaoh is depicted as a journey through the rituals which surround his initiation into temple life. In death, the Pharaoh continues his journey in the Underworld in the boat of the Sun God Ra, travelling through the twelve hours of night and conquering the powers of darkness before being resurrected at the dawn of the new day.
