Arch rivals for over forty years, equestrian icons Alfred McDonnell and Cora Stuart decide to hang up their spurs with a showdown: one rider, one horse, one groom/assistant and one class the puissance wall. Alfred's plan is to keep Cora guessing. His rider, Terri Page, as well as the horse, Green Luck, have been kept under wraps. Tight wraps. So when Alfred asks Robert Bromwell, a well-known veterinarian, to be Terri's assistant, Robert jokingly offers to wear a disguise. In keeping with his guessing game, Alfred takes him up on his offer. Little does Robert know that Terri, plagued by past experience, is big on the truth, the whole truth and nothing but. He also hasn't planned on her capturing his long-denied heart. Now Robert Bromwell, DVM, alias Clay Moore, is headed for a showdown of his own.
