As described in a film magazine, Katherine Bush (Calvert), a young woman from London's lower middle class, yearns for the finer things in life and spends an illicit weekend with a certain Lord Algy (Goldsworthy) at a fashionable watering place. Returning home, she answers an advertisement that leads to a position as secretary to Lady Garrubardine (Brundage), a leader of London society. Lord Gerald Strobridge (Kent), Lady Garrubardine's unhappily married nephew, falls in love with Katherine but she only offers him friendship. Katherine rises in Lady Garrubardine's estimation until she is almost an equal in the household. Then comes the Duke of Mordryn (Burton), a statesman who falls in love with Katherine, believing she is of his class. Learning the truth of her station, he continues his attentions and finally proposes. Katherine then tells him of her one misstep. He leaves her at once. Then Lord Gerald leaves for India, and Katherine believes the end of her dream of happiness has come. Lady Garrubardine, however, intervenes in her behalf, and the Duke comes to her, forgiving, and they are married.
