An elderly Irishman, Finian, moves to the southern United States with his daughter Sharon, to bury a stolen pot of gold near Fort Knox, in the mistaken belief that it will grow. Og, a leprechaun, follows them, desperate to recover his treasure before the loss of it turns him permanently human. Complications arise when a bigoted and corrupt U.S. Senator gets involved, and when wishes are made inadvertently over the hidden crock. The Irish-tinged music score includes gospel and R&B influences.
