Karen and Lash meet as teenagers and form an immediate bond over their mutual love for horses. Year later, Lash marries, and she and her husband locate their dream acreage for building a home and an equestrian facility, only Lash's dream isn't complete if she can't convince Karen to risk everything in a purchase of the adjoining property. Karen eventually gambles it all, and together, she and Lash weather countless falls from horses, a roller coaster of love losses and triumphs, the emotional pitfalls of equestrian breeding and competing-and finally, a heartbreaking diagnosis of a fatal illness.
