Sex. Money. Horses. Every year, on Valentine's Day, the great Thoroughbred farms open their breeding sheds and begin their primary business. For the next one hundred and fifty days, the cries of stallions and the vigorous encouragement of their handlers echo through breeding country, from the gentle hills of Kentucky to the rich valleys of California.Studtakes us into this strange and seductive world of horse breeding. We meet the world's leading sire, Storm Cat, the Triple Crown winner, Seattle Slew, and a nearly unmanageable colt, Devil Begone, who has found peace and prosperity on the banks of the Rio Grande servicing desert mares like Patty O'Furniture. Cheap stud, top stud, old stud, wild stud, from the Hall of Fame horse to the harem stallion with his feral herd, Stud looks at intimate acts in idyllic settings and the billion-dollar business behind them.
