Watch full movie online. Kasper Mai, an export merchant and comrade with a “clean” record, discovers he is the prince of Hohenlohe-Liebenstein. His royal grandmother designates him as the heir to her estate. A private trip to her reveals that she does not want a NATO airbase built on her land. The GDR and his grandmother thus find a common interest, and a clever lawyer from the East works against other family members looking to settle their debts with the estate money.
