Jan Hardy wants to train racehorses to win. And with her profesional training license under her belt, she visits Ireland to buy horses at auction. But she finds out more than she bargains for in the shape of influential tycoon A. D. O'Hagan.

As money worries pile up and family affairs run far from smoothly, Jan comes to depend on the friendship and support of Angie Sharp, herself no stranger to the racing business, who persuades her parents to appoint Jan as their new trainer.

With the support of O'Hagan, Jan builds up a string of racehorses and her jockey starts to win races. While her reputation begins to soar, family troubles still demand her attention - as does the local GP, Doctor Tony Robinson, who wants to give her more than just his loyalty. Then as her jockey inexplicably loses his winning touch, life appears to spiral out of control. And a mysterious person from Jan's past is waiting in the wings . . .
