Persuaded by a letter from her Aunt Agnes in America, Kitty McCarthy ( Olive Thomas ) travels from Ireland to New York City, there she meets Gordon Davis, a successful playwright, who directs her to her aunt's address on the East Side. Kitty soon discovers her aunt living in a tenement, a confirmed alcoholic. Through her niece's care, Agnes is cured, and one day Davis appears and offers Kitty a part in a comedy that he has written. She accepts, and once backstage meets Vera Maxwell, the victim of an unhappy affair with Oscar Savoy. Kitty brings the lovelorn couple back together but is unsuccessful in arranging her own romance with Davis' nephew Roger until Davis finally intervenes, and a happy ending prevails for all.
