A young princess, Fairer-than-a-Fairy, is kidnapped by a jealous, mean, old fairy named Lagree, who locks her away because none of the fairies can stand to have a mortal girl said to be more beautiful than them. Lagree locks her away in a palace, with her dog and cat, and tells her to tend to a fire and to never let it burn out. In her solitude, she one day meets a prince whom Lagree has captured and changed into the form of a rainbow that she discovers in a fountain. Rainbow and Fairer-than-a-Fairy fall in love and are forced through some trials and tribulations to find their happy ending.
