Apfelland is a small yet beautiful nation bordered by Russia, Austria, and Germany. Vel is a boy residing in the capital, Charlottenburg. He happens to assist a girl named Frid. She was kidnapped because a radium deposit was discovered in her grandfather's abandoned mine. Various individuals converge on the site, drawn by the radium: for instance, an American seeking profit, a Polish woman disguised as a man aiming to fund the revolution, and the Apfelland ministry plotting to affiliate with Germany. Vel and Frida become entangled in these schemes, and they are aware of the mine's secret. (From AnimeNfo)
