A loose continuation of the cases of our murder squad in the films Škodná and Hrobník. The new film not only deals with the murder of a psychologist, reminiscent in some respects of a deviant crime with bizarre ritual elements. We also follow the fate of Drobný, a recently released prisoner who is convinced that he has a profound reason to hate the psychologist and take revenge on her. Gradually, he finds himself in the position of a cornered animal, which only intensifies his desire for harsh retribution. The first storyline of the film is purely detective-like, while Drobný's story is more in the style of a gritty crime thriller.

Luckily, there is a young man named Libor who will do anything to protect the whole village, and especially Karolínka, from the water sprite villain. So what if he has to scheme and lie? The main thing is that he can get Karolínka to reject Jonáš and choose him, the brave Libor, instead.

Intolerance can already be ominously growing among children. Even the talented Petr, who is not accepted by his new classmates, will be convinced of this - he only encounters rejection and even betrayal of trust. More than exposing children's mentalities, however, the creators are trying to present a model of social morality, which, however, lacks both a more credible motivational background in the actions of the individual characters and the courage to point out the functioning of deformed relationships. However, they unfortunately did not reach the level and communication of Schorm's film Five Girls on the Neck, which dealt with a similar problem.
