The story of urban boys, brothers Jakub, 17, and Mato, 10, who spend their summer holidays at their grandmother's house in the countryside: the younger one voluntarily, even though his summer well-being is spoiled by maths tutoring, the older one involuntarily, because he had other plans for the holidays. As the summer days pass, however, both boys' plans and moods change. While Jakub is experiencing his first serious emotional relationship with the pretty Renko, the younger Mato and his local friend, the mentally challenged Misha Bomba, are undertaking tajo.
