An ageing singer asks for shelter at Newark Castle, and in exchange performs for his hostess the Duchess of Buccleuch the story of a 16th century border feud. The story he tells is about the so-called "Flower of Teviot," the Lady Margaret Scott of Buccleuch, who the Baron Henry of Cranstown is in love with. But whilst Henry is from the Ker Clan, Margaret is from the Scott clan, and the two families are in the midst of a vicious border war. This conflict has recently caused the death of Margaret's father, and as such, her mother is fervently against the union of the two lovers. Scott spent a lot of his career collecting traditional ballads and studying local legends and folklore, which he masterfully weaves into this gothic romance.
