Mrs. Anna Leonowens and her son Louis arrive in Bangkok, where she has contracted to teach English to the children of the royal household. She threatens to leave when the house she had been promised is not available, but falls in love with the children. A new slave, a gift of a vassal king, translates "Uncle Tom's Cabin" into a Siamese ballet, expressing her unhappiness at being with the King. She attempts to escape with her lover. Anna and the King fall in love, but her British upbringing inhibits her from joining his harem.
