Poor inventor Michael O'Reilly (Pearce) is an immigrant from Ireland living in the United States. When he suddenly comes into money, he sends his daughter Patsy (Love) is sent to an exclusive boarding school. The snobby students shun her until she claims to be an Irish princess, and they then demand to see her coat of arms. To meet this need, her father buys the family heirlooms of the destitute Irish Windbourne estate.
Lord Windbourne (Wetherby) himself appears and becomes engaged to Patsy, with the intention of reclaiming his treasures and her fortune. When she learns his true character, she breaks the engagement, but Windbourne threatens to reveal the O'Reillys' deception.
Handsome young Irishman Larry Burke (Gordon) appears with proof that he is the real Lord Windbourne. He proposes to Patsy, who accepts.[3][6][7][8]
The film received generally positive reviews, although the story was deemed predictable.[6][8][9][10][11][12] It was commercially successful.[9][12] The photography was highly praised,[6] as was the acting,[3] in particular that of Bessie Love.[13][14][15]
