In the spring of 1926, the Soderbjerg brothers, Ray and Roy, plunge into radio and launch station WLT (With Lettuce and Tomato) to rescuer their failing restaurant and become the Sandwich Kings of South Minneapolis. For the next quarter century, the "Friendly Neighbor" station produces a dazzling array of shows and stars, including Leo LaValley, Dad Benson, Wingo Beals, Slim Graves and Little Buddy, chain-smoking child star Marjery Moore, and blind baseball announcer Buck Steller. Francis With, a shy young man from North Dakota, entranced by radio, gets into WLT through his uncle Art and quickly becomes the Soderbjerg's right hand. Soon Francis is a budding announcer adored by Lily Dale, the crippled nightingale of WLT kept hidden from her fans, whose firing contributes to the downfall of the station. And then comes television.
