High-spirited Perdita Wentworth is incensed when she overhears Lord Rushmore casting disparaging remarks about the young debutantes at Almacks. While she makes every effort to insult him, her behavior ends up threatening her reputation. When her parents send her to Bath to re-think her future, she befriends Rushmore's ward, Louise - a wealthy heiress - who has attracted a handsome fortune-hunter. When Perdita and Rushmore join forces to thwart Louise's beau, she starts to realize that perhaps she has misjudged the handsome nobleman.
