Traveling in Ireland, New York reporter Stephen "Fitz" Fitzgerald (Tyrone Power) befriends a leprechaun named Horace (Cecil Kellaway) by refusing to take his pot of gold. Back home, Fitz takes a job for D.C. Augur (Lee J. Cobb), a publisher with political ambitions and the father of his fiancée (Jayne Meadows). Soon, Horace reappears in Fitz's life, in the guise of a valet, to push him toward a romance with Irish girl Nora (Anne Baxter) and a job that doesn't compromise his principles.
