After WW II many young people arrive to Zagreb, among them a young worker Sonja Kacar. She is supposed to participate in the construction of the first generator in the Rade Koncar factory. Because there aren't enough experts and materials in Yugoslavia, the factory counts on help from fellow communist countries, Czechoslovakia and Soviet Union. However, after the Inform Bureau's resolution this help is no longer available. Sonja experiences a great intimate disappointment because Stjepan, who she is in love with, supports Stalin.
The setting is a Central European kingdom, near the turn of the century. Bored by his very proper wife, the youthful heir to the throne spends his time in amorous dalliances at a sprawling country estate. His wife departs at the arrival of his friends, and they organize a celebration which becomes a wild orgy and culminates in death and tragedy.
