Seventh form pupils at a grammar school in Přívlaky are preparing for a secondary school sports competition. Class creep Krhounek gives the class teacher Lejsal a copy of the seventh form’s magazine Roar. Most of the teachers insist on severe punishing the culprit. The author does not own up and consequently the whole class is punished by being banned from taking part in the schools competition. The most gifted pupil, Benetka, rather sharply criticises the school in a homework essay on a subject of his choice. The strict Czech language teacher is convinced Benetka is the author of the school magazine. Benetka denies the charge but his expulsion from school is proposed anyway on account the views he expounded in his essay. Eventually, Boukal, the author of the school magazine comes forward and admits to writing it. The pupils are allowed to take part in the contest and thanks to Benetka they win. In the meantime however the teachers vote to expell him.
