Isabel Archer is a young, intelligent, and spirited American girl, determined to relish her first experience of Europe. She rejects two eligible suitors in her fervent commitment to liberty and independence, declaring that she will never marry. Thanks to the generosity of her devoted cousin Ralph, she is free to make her own choice about her destiny. Yet in the intoxicating worlds of Paris, Florence, and Rome, her fond illusions of self-reliance are twisted by the machinations of her friends and apparent allies. What had seemed to be a vista of infinite promise steadily closes around her and becomes instead a 'house of suffocation'.
