A wealthy young heiress embraces social reform and suffrage, challenging her conservative family and established expectations. She moves between fashionable social life and earnest political meetings, reading radical writers, organizing petitions, and delivering speeches to working-class audiences. The story follows her efforts to reconcile public activism with private desires, including questions of love and marriage, while peers and relatives alternately mock and admire her convictions. Through scenes of salons, club meetings, and public addresses, the narrative explores class privilege, performative philanthropy, gender roles, and the personal costs of committed reform.
