Sbórnia is a small country that has always been isolated from the rest of the world, surrounded by a large wall that does not allow its contact with the neighbors. One day, however, an accident leads to the fall of the wall, and later the sbornians begin to discover the modern customs. Two local musicians, Kraunus and Pletskaya, observe the reactions of their countrymen: while some quickly adopt foreign culture, others prefer to reaffirm the sbornians traditions and resist imperialism.
