On Highway 57, somewhere in North Carolina, stands a gas station. Across the blacktop is a roadside eatery called the Double Cupp Diner. The four guys at the station, Jim, Jackson, Eddie and L.M., have been known to do some auto repairs, but only when aided by quantities of time and libations. The Cupp sisters, Prudie and Rhetta, celebrate their home cooking with the same zeal they bring to being neighborly with the boys. With heartbreak and hilarity, this is a musical tribute to life by the roadside!
