Desc: What Every Woman Knows: Directed by William C. de Mille. With Lois Wilson, Conrad Nagel, Charles Ogle, Fred Huntley. In England, railroad porter John Shand is offered an education by wealthy Alick Wylie on the condition that he marry his benefactor's daughter Maggie within five years. John keeps his promise and is later elected to the House of Commons. Although he achieves fame through the wit and wisdom Maggie secretly adds to his speeches, John falls in love with Lady Sybil. Unaware of the infatuation, Maggie arranges for them to visit a country estate. John prepares a lackluster speech for a cabinet minister, which is a success--after Maggie rewrites it. He then becomes aware of her devotion to him, and how much he owes his position to her.
