Years pass and Rameses is named the new Prince Regent to oversee the construction of all temples. Proud of his brother's new post, Moses calls for a celebration. The High Priests Hotep and Huy present Rameses with a special gift -- Tzipporah. Rameses, in turn, awards her to Moses, and orders her taken to his room. Rameses then proudly appoints his brother as his assistant.

That night Moses discovers that Tzipporah has escaped. He follows her and comes upon his true siblings, Miriam and Aaron.

Believing that Moses has returned to help them, Miriam reveals to Moses the truth about his identity. Shocked and dismayed, Moses refuses to believe her and flees back to the palace. The next day he confronts his father the Pharaoh Seti and recoils from the Pharaoh's cruelty toward the Herbrews.

Moses sees for the first time the brutal lives of the Hebrew slaves. A palace guard strikes an elderly Hebrew man. Moses leaps to the old man's defense, causing the guard to fall to his death. Stunned by his own actions, Moses flees into the desert.

As Moses trudges through the desert, he removes the trappings of his palace life. He encounters Tzipporah and her family. As the years pass, Moses and Tzipporah fall in love and build a contented life as humble shepherds. One day as Moses goes in search of a wayward sheep, he comes across a burning bush that is not consumed by the flames. To Moses' amazement, he hears the voice of God, calling upon him to return to Egypt and free the Hebrew people.

Moses returns to Egypt, where he discovers Rameses has become Pharaoh. Rameses is overjoyed by his brother's return. But when Moses tells him about his mission to free the Hebrew slaves, Rameses reacts with disbelief and scorn. Though Moses tries to convince Rameses of God's power, Rameses is unimpressed.

Finally, as Moses warned Rameses, God brings a series of plagues to overrun the land. Although the Egyptian people become more and more afflicted by disease, famine and pestilence, Rameses refuses to give in. That night, God speaks to Moses, warning him of one final plague.
