Czech nobleman Petr Vok of Rozmberk (Milos Kopecký) is no longer so young, but his amatory adventures continue to arouse the envy of men and the indignation of respectable ladies. In his "female retinue" at the chateau in Bechyne he has twelve comely girls, but he still manages to seduce the miller's wife and the maid. Lord Vok is in great financial difficulties. His elder brother Vilém advises him to marry a rich woman. Petr surprises him by announcing his intention to marry the very young Katerina of Ludanice.
Marido (alto funcionário do ministério) e mulher encontram a sua casa repleta de dispositivos de escuta colocados lá pelo seu próprio ministério. Segue-se ma noite angustiante (uma reminiscência de 'Quem Tem Medo de Virginia Woolf'), e a resolução é pior do que serem levados para a prisão. (e 12 - Estimado 12 Anos)
