A melodramatized biography of Leonard Slye, who became the cowboy who captures the hearts of millions, starts in the earliest days of his Ohio childhood. Born in a Cincinnati tenement, young Leonard was soon introduced to a happier life, first aboard a house boat on the Ohio River, and then on a farm where an early start in 4-H activities strengthened the simple religion that became a prominent part of his life. There, Leonard discovered musical talents as well. They came naturally, for his father played the guitar and the mandolin, so, after a first job in a shoe factory, Leonard started out with a group of western singers and players and finally broke into Hollywood as Roy Rogers. With his faith in prayer as strong as it is, it had been rumored that Roy would go into preaching. But he says he can do more through show business and, indeed, his way with fans has become all but a religion.
