What Fools Men Are (1922)

Pleasure is the watchword- studio parties in Greenwich Village, expensive restaurant dinners, dancing till the wee small hours, and CLOTHES!

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.
