Tomáš is a Czech surgeon, who after the Russian invasion, escaped to Geneva with his wife, Tereza. When Tereza returns to Prague, Tomáš eventually follows her back. There, he is forced to answer for a letter to the editor he had previously written criticizing Czech Communists. Later, he and Tereza move the countryside where he lives out the rest of his life.

His epitaph reads "He Wanted the Kingdom of God on Earth."
