Artist Pietro Leoni is preoccupied with feminine beauty. While walking near an old castle in Italy, he sees a young woman dive in the water from a rock and becomes determined to sculpt her from memory. He rents a house near the spot and falls in love with the mentally disturbed daughter, Francesca, of the castle's owner, W. C. Hutton, while becoming involved with her sister, Marisa unaware of her identity.
