Beautiful Lady Kathleen Malloy is a spectacular horsewoman but used only to life in the backwater of her father’s Irish estate. When two London gentlemen visit to look over some horses, she is chagrined to hear them dismiss her for her lack of manners and polish. Determined to prove them wrong, she travels to England to see if her grandmother will sponsor her come-out. As she takes London by storm, she finds that she still hopes to turn the head of at least one of the men who met her in Ireland, the handsome aristocrat Lord Giles.
