A mysterious Irishman, Finian, and his beautiful daughter Sharon arrive one day in a small Southern town of sharecroppers. The town has its own dreamer who thinks that he might be able to put the town on the map by crossing mint with tobacco so that it'll come mentholated. Fianian's journeyed to the town because he's captured a leprechaun's crock of gold and plans to plant it in the ground so it'll grow faster (or else why would the Americans have rushed to dig the gold out of California only to plant it back in the ground at Fort Knox?). But Og the leprechaun arrives, bent on retrieving his gold. Meanwhile, the bigoted Judge Hawkins is upset with the tobacco growers because they're not segregated, and plans on taking their land away. And when Sharon yells, "I wish to God you were black so you could know how it feels..." while standing right over the pot of gold, all hell breaks loose as wishes come true.
