Harry Clay Blaney

Four "Picture Brides", from New Orleans, arrive in the Brazilian jungle on a riverboat, brought there to marry workers at Lottagrasso, a remote mining site of the Standard Diamond Mines. Also on the boat with the four "mail-order" brides (Americans Mame Smith, Flo Lane, and Gwen from England and Lena from Europe) is Mary Lee, a frightened and innocent girl, who has come to see the mine's brutal supervisor, Von Luden, about a job.

Kate Claybourne is too busy with her literary career to notice that her husband, Bartley, is providing the finery for her flapper sister, Peggy Kendricks. When she does find out, she seeks a divorce, with the understanding that Bartley will marry Peggy. But Peggy, who toys with many men's hearts, marries Ralph Demarest, thereby cutting off Ralph from his disapproving father's fortune. Peggy accepts money from Horace Demarest to leave Ralph but then flings it in Ralph's face and urges him to make a man of himself. Peggy stands by Ralph, wins Horace's affection, and reunites the Claybournes.
