This tale is about young Ludvik (Robert Nespor) an erstwhile, budding scientist whose practical sense leads him to experiment before his common sense has figured out the results. Due to that unfortunate pattern, he variously floods the bathroom while working on displacement of volume and weight in water, he shatters the harvest pumpkins but not the law of gravity, and now he is eyeing the neighbor's rabbits for an electricity experiment. While the rabbits remain safe for awhile, Ludvik's parents wish he would follow in their more traditional footsteps and dedicate himself to music. Instead, Ludvik has learned that the proper mixture of a certain carbide and water can be explosive, and while he works on that technique, a friend tips off the physics teacher about these potentially disastrous plans.

In one royal forest, where coal miner Patočka lives and works, the friendly dragon Mrak settles down. The king's lackeys come across him while hunting and, terrified, go to sell the news to the king. He is currently organizing his daughter Viola's birthday party. The hunters describe the dragon in terrifying colors, and so the king concludes that the dragon will, according to tradition, want the king's daughter. So he announces a reward for killing the dragon, but no one wants to fight him. The only one who applies is the princess's favorite, the lutenist Marian, but the king does not like him, so he throws him out. Her brother Jan wants to save the princess, but the king doesn't want to allow it...

Two somewhat crazy friends Milan (Milan Lasica) and Julo (Július Satinský) resolve to have a peaceful holiday in an old guard house that Julo has bought from his uncle. But in the early hours of the very first morning they are woken up by the loud sound of a trumpet. It is the severe supervisor of a nearby recreation center forcing the children out of their beds and out to exercise drill. To protect themselves from the children, Milan and Julo put up signs saying "private property". The first to disturb their privacy is the supervisor's little granddaughter Miluska, who uses their shed as her gingerbread house. The children in the camp are disgruntled, the supervisor's program bores them, and so they make up all sorts of other things to do.

Hockey requires great commitment and even sacrifice from an early age. The thirteen-year-old players of a school hockey team, led by an experienced and perceptive coach, struggle with various problems of their age, from first loves to low self-confidence and disciplinary problems, but in the end they are all consumed by a sense of responsibility.
