Gosford Park (2001)

Set in the 1930s, the story takes place in an old-fashioned English country house where a weekend shooting party is underway. The story centers on the McCordle family, particularly the man of the house, William McCordle. Getting on in years, William has become benefactor to many of his relatives and friends. As the weekend goes on, secrets are revealed, and it seems everyone, above stairs and below, wants a piece of William and his money, but how far will they go to get it?
