Think the Kardashians are the most dramatic, scandalous family you've seen? Meet the Mitfords, the real-life inspiration behind Marie Benedict's "The Mitford Affair." In the years leading up to World War II, the glamorous Mitford sisters are the talk of high society. Nancy Mitford, a novelist, soon becomes alarmed at the actions of two of her sisters: one divorces her rich and powerful husband to marry a leader of the British fascist movement, and another, infatuated with Hitler, travels to Germany to ingratiate herself into his inner circle. When Nancy learns the true extent of her sisters' choices, she's faced with a dangerous choice to either betray her family or betray her country.
