David Graham's wife Marie is so devoted to him that he wearies of her constant attempts to please him--and criticizes her. Sara, a former sweetheart of his who selfishly married for wealth, secretly determines to lure him from Marie. When forced to keep an overnight business engagement, Daly invites the Grahams to keep his wife company, and Sara writes David begging him to see her alone--but Marie intercepts her letter. When the Grahams accept the invitation, Marie confronts Sara with the unopened evidence. Discovering the plot, David denounces Mrs. Daly and reaffirms his love for Marie.—AFI
