UK hit-maker and Eurovison songwriter Ricardo Autobahn follows the synthesizer pop duo Hyperbubble, described by Alternative Press as "the sonic equivalent of a truckload of Twizzlers", as they drive to Nashville to record a country and western album using only synthesizers, drum machines, and theremin. Along the way, Hyperbubble members Jess and Jeff meet cartoon cult heroes Samantha Newark of Jem and the Holograms and Manda Rin of Bis/Powerpuff Girls fame, Theremin diva Dorit Chrysler, music fashion guru Manuel Cuevas, cosmic cowboy Garett T Capps, air-drumming filmmaker Ari Gold, Do-It-Yourself vinyl pioneers Shoes, synth-pop sweeties Freezepop, Lederhosen Lucil, Helen Love, and Our Daughters Wedding, and somehow end up winners in Dolly Parton's Netflix song contest.
