Concern for a despondent thoroughbred filly draws trainer Joan Caulder and gallop girl Cailen Eagleton into intimate daily contact. But Cailen believes she isn't free to act on her growing attraction, and Joan is too principled to push for answers to what "not free" means in Cailen's case. Just as they're figuring things out, Joan and Cailen are forced to attempt a desperate heist when the jealous owner of the filly they love threatens to sell the horse for slaughter unless Cailen exits Joan's life forever. Risking charges of grand theft, Joan, Cailen and their unforgettable friends devise a high-risk plan to steal a half-ton, high-strung racehorse from the stone, steel and electronic embrace of the high-tech security team at opulent Rainier Farms.
