Jenny (Cathryn Harrison) lost her mother in a horse-riding accident, so her father strenuously disapproves of her intention to pursue horse jumping. She leaves home and begins her goal at the bottom, shoveling out the racetrack's stables. She becomes obsessed with Blue Fire Lady, a half-crazy racehorse that only lets Jenny handle her. A jockey abuses the horse, and Blue Fire Lady winds up for sale. It's up to Jenny to somehow buy her and prove everyone wrong.
