Homecoming to the Bohemian Province. In the spring of 1896, a carriage rolls up to Ronsperg Castle in the Bohemian Forest: Count Heinrich Coudenhove-Kalergi returns to his homeland after years in the Emperor's diplomatic service. He is accompanied by his Japanese wife Mitsuko, whose exotic appearance causes a stir everywhere, and his sons Richard and Johannes. The story of a fascinating family. Many years later, the older of the two, Johannes, waits in a barrack of a Czech internment camp for his deportation to Bavaria. Due to the Benes Decrees, the Coudenhove-Kalergi family has lost everything they once owned - except for their great history. And so Count Hansi tells his fellow sufferers about the fates of his family: about the cosmopolitan atmosphere that always prevails at Ronsperg Castle; about the revolutionary ideas.
