Czechoslovakia, 1963. Jan Díte is released from prison after serving 15 years. He goes into semi exile in a deserted village near the German border.

Thanks to a patron, he becomes a waiter at upscale hotels and restaurants. We see him discover how the wealthy tick and how to please women. He strives to be a millionaire with his own hotel. Before the war, he meets Líza, a German woman in Prague. Is this his ticket to wealth or his undoing? Meanwhile, we see Jan putting a life together after prison: why was he sentenced, and who will he become?
