A 15-year-old girl named Cassie is an all-around city girl. Her single mother has to go to England on business and she doesn't want Cassie to cause trouble there so she sends her to stay with her Aunt and Uncle on their ranch in the country. She gets there (not at all happily of course!) and meets Rafe a young guy who works there. She also hears about and sees Kia, a pretty much wild and untrained beautiful purebred black horse.
