Joseph (voice of BEN AFFLECK, singing voice of DAVID CAMPBELL) is the youngest son of Jacob (RICHARD HERD), a sheepherder who believed that his new wife, Rachel (voice of MAUREEN McGOVERN), was unable to have any children. As a result, Jacob considers Joseph a miracle child, and thus doesn't treat him like his many other sons, including Judah (voice of MARK HAMILL) and Simeon (voice of STEVEN WEBER), who are jealous of their younger brother and the preferential treatment he receives.
Despite that and his ability to interpret dreams and their forecasting of the future, Joseph longs to be with and be treated like his brothers. Unfortunately, that's his undoing as unbeknownst to Jacob, they decide to sell him into slavery. Taken from Canaan to Egypt, he's sold to Potiphar (voice of JAMES ECKHOUSE), a high-ranking official working for the Pharaoh (voice of RICHARD McGONAGLE), to be used as domestic help rather than as a laborer.
Although he quickly impresses Potiphar, when he refuses the amorous advances of that man's wife, Zuleika (voice of JUDITH LIGHT), she wrongly accuses him of an injustice and he ends up being sent to prison. As the years pass and he's befriended by Asenath (voice of JODI BENSON), who sneaks him food, Joseph learns the meaning of forgiveness and is eventually called to interpret the dreams of the Pharaoh.
Successfully doing just that and saving the people of Egypt from a severe famine, the Pharaoh appoints Joseph as the second most powerful man in the land. As he then gets on with his life, not believing the good fortune that's come his way, he must contend with his brothers when they unexpectedly return into his life.
