I really enjoyed this movie. Based upon the true life of Duchess of Devonshire, Georgiana Cavendish, The Duchess is a fascinating tale developed from the novel written by Amanda Foreman (you can bet your sweet cheeks I'm buying that book ASAP).
Georgiana has 2 girls and hovering always in her mind is the male heir that she cannot produce. On a trip to Bath, Georgiana meets Lady Elizabeth Foster, a woman who's husband has taken her 3 children away from her and beats her. Georgiana invites Elizabeth to stay with them and eventually William and Elizabeth begin an affair. Georgiana is heartbroken that her husband has stolen her friend, and is further depressed when William refuses to send Elizabeth away and actually moves her 3 young sons into their home.
