A group of high school seniors begin arguing at their graduation party about how to get hold of the exam questions. Martin, who is known for his knowledge and skills in cybernetics and computers, bets the others that he can download the questions from the Ministry of Education's server. The other students are counting on Martin to download the questions, so they don't prepare much for the exam. However, Martin is unable to access the questions, so he and his classmates break into the ministry building. But even here, the students are unsuccessful. Meanwhile, IT staff at the ministry discover that someone has hacked into their server. They inform the police. The final exams begin. Even though Martin did not download the correct questions from the server, all the students pass their exams because the teachers are even more eccentric than the students themselves.

Ten years later, the people of Kamenákov are still stirring up trouble, including Pepa, who is now mayor and trying to establish a police force.
