František Cepl is a young man from a simple family. He graduated from a real school and was going to study technology. When the occupation came, he had to work as a factory assistant. There he meets an older man named Telec, whom everyone knows as Hrabě. He impresses František with his ostentatious disdain for work and his shameless flirtation with women. František, whom the Count calls Papilio (butterfly butterfly), is filled with youthful ideals, while the Count, on the other hand, is an extract of the crudest individualism. He has worked his way up from a student at a business academy and a theatre actor to a member of a pre-war gallery. He blackmails, steals, drinks, abuses women and, in a way, Papilio himself.
