Elizabeth Browne is the daughter of nouveau riche parents, who became wealthy when they struck oil. While she attends finishing school, her folks travel to England in search of a family tree so that they can enter society. They encounter Lady Dysart, an adventuress who married Lord Dysart shortly before his death. Lady Dysart tries to convince the Brownes that Cecil, her son from a previous marriage, is the new Lord Dysart.
