A film in five episodes, all based on an attempt to show the life of young people today, their feelings and relationships, their behaviour in public and private life.

During the Nazi occupation of a Czech city civilians are being rounded up on the slightest of pretexts and shot. One day three high school boys who crack jokes about a recently deceased "hero of the Reich" are pulled out of school by the Gestapo.

A student work by Jiří Menzel, filmed during his second year at the FAMU film school. Views of old Prague and its tenement buildings, symbolizing the obsolete past, alternate with shots of construction sites for new prefabricated apartment buildings. In spite of certain unavoidable propagandistic overtones added by the director, it is notable as the beginning of his search for a “dramaturgy of colors.”
