In 1875, Clio Dulaine (Ingrid Bergman), the illegitimate daughter of an aristocratic New Orleans Creole man and a French woman, returns from Paris to her birthplace to avenge her mother’s mistreatment at the hands of her father’s family. However, she faces a dilemma when she falls for a tall Texan with his own agenda for revenge on the railroaders who ruined his father.
Clio is accompanied by her interfering mulatto maid, Angelique (Flora Robson), and a dwarf manservant.
The Saratoga Trunk is a railway line which suddenly becomes worth millions of dollars because it connects the coal country with New York.
Flora Robson was nominated for an Oscar for Best Actress in a Supporting Role for her performance as Angelique.
