In the backwoods of Tennessee, country singer Woody Weatherby receives word that he has inherited a casino in Las Vegas. Elated, Woody and his buddy Jeepers head for Nevada in their dilapidated jalopy Lightnin'. When they arrive, they find that their bonanza is nothing but a debt-ridden dive. Enlisting the aid of Jayne Mansfield and Mamie Van Doren, the boys are determined to make Woody's Golden Circle a success. Jayne is hired to manage the gambling concession while Mamie is supposed to be a singer, but most of the time they just hang around and look pretty (so what's wrong with that?). But it takes the shrewd business sense of Aunt Clem from back home to make the place really take off. She books the finest talents in country music for the entertainment, and their appearances form the true high points of the picture.
