Howard Allen, Mrs. Sinclair's brother, tries to dissuade his sister from forming an alliance with Randall, but the suave manners of the latter have made a strong impression upon the susceptible woman. Mrs. Sinclair has two young children, Grace and Freddy, whom she loves very dearly, but she becomes remiss in her attentions to them because of the time which she spends in Randall's company.
