She'll go straight to your heart with her laughs, her tears, her songs. Sad moments, glad moments, they're all here in the story of the immortal Peg that has won the heart of the world.

Peg and her father live a simple life in an Irish fishing village. One day Sir Gerald arrives at the village to tell Pat that Peg is heir to estate of her grandfather, who hated Pat. The upshot of the will is that she must go to England for 3 years to learn to be a lady and that Pat can never see her again.
