The film depicts Joseph and the Amazing Technicolor Dreamcoat being performed to a primary school assembly hall, where the children become the chorus of the musical while the teachers and staff become its characters.
Impressed, Pharaoh puts Joseph in charge of planning for the famine, and he rises to Vizier of Egypt.
Back in Canaan, Joseph's family are suffering in the famine, and his brothers begin to regret their actions.
He tests them by setting up the youngest, Benjamin, to accuse him of theft, and the brothers beg Joseph to let him go.
The release of the film was advertised by a brief series of sing-along performances that Osmond starred in as a Fathom Event.
