Nicola Sullivan is an aspiring young trainer, certain that given the right horses she is as good as anyone in the business. Until, that is, an owner removes two horses to another yard, and one shows dramatic improvement. She enlists the help of her brother, Jamie, once a star flat jockey, now trying to revive his racing career over fences after a harrowing term in prison. But former wild boy Jamie has his own demons to deal with, like the new challenge of jumps riding, the hostility of those who can never forgive him for a young lad's death - and the black wall within him that separates him from his past.
