The movie Prince of Egypt (1998) opens with the culling of the Hebrew slaves' newborn sons and introduces the hero, Moses, as a baby sent into the river by his mother in hopes of saving him. We witness the adoption of Moses into the royal family, and we are aware that his sister, Miriam, knows that the second prince of Egypt is her younger brother.
There is a time skip, and we see Moses and his elder adopted brother, Ramses, as mischievous young princes. Later, we are introduced to Tzipporah, who was captured in the desert and given to Moses by his brother. When she escapes from the palace, Moses follows her and runs into his biological siblings. His sister, Miriam, attempts to convince him of their sibling relationship, but he refuses to believe her until she sings their mother’s lullaby, introduced at the very beginning of the film, and Moses flees.
Moses then returns to the palace and confirms the truth of his past with his adoptive parents, but he also learns of the atrocities committed against the slaves by the pharaoh. Unable to stomach the abuse of the slaves now that he knows of his heritage, Moses attacks and kills an Egyptian overseer and escapes into the desert.
After nearly perishing in the desert, Moses is discovered by Tzipporah after saving her sisters from brigands. Moses is welcomed into the desert clan's way of life by Tzipporah's father, Jethro, and Moses eventually marries Tzipporah and becomes a shepherd. However, one day he is visited by a vision of God informing him that he is destined to free the slaves from Egypt and deliver them to the Promised Land.
Moses does as instructed and returns to Egypt with Tzipporah. He greets his elder brother, who is now Pharaoh, but is unable to convince his brother to let the slaves of Egypt free. The relationship between them sours as Moses continuously demands the Hebrews be set free, which enrages Ramses and incites him into treating the slaves more cruelly than before.
Moses inflicts nine of the ten plagues on the Egyptians, but when Ramses still refuses to set the Hebrews free, he inflicts the final plague on Egypt, the death of firstborn children of households not marked with the blood of a sacrificed lamb. After the death of his son, Ramses allows Moses to free the Hebrews.
Moses leads the freed slaves from Egypt, but when they reach the Red Sea, they quickly discover that a vengeful Ramses is set on hunting them down. A pillar of fire blocks the way for the Egyptians, and this allows Moses to part the Red Sea so that the Hebrews can escape to the Promised Land.
