The Wise Wife.

John Blaisdell, a stolid businessman married for 10 years, concludes that romantic love is a thing of the past for him. His wife, Helen, a very domestic and conservative woman, invites Jenny Lou, a young southern girl, as her houseguest, and the girl flirts with John; she is conspicuously unsuccessful until she pretends to faint on the golf course and the unsuspecting victim finds her in his arms.
