Set in the years before and during World War I, this epic tale tells the story of a rich Argentine family, one of its two descending branches being half of French heritage, the other being half German. Following the death of the family patriarch, the man's two daughters and their families resettle to France and Germany, respectively. In time the Great War breaks out, putting members of the family on opposing sides.

A young woman, Margaret Dauncey, is caught between the forces of a charlatan magician, Oliver Haddo, whom she is unable to resist, and the love of a handsome surgeon, Arthur Burdon, who has saved her from being a helpless cripple by performing a delicate operation on her spine.

1932 film by Rex Ingram and Alice Terry
