An adventure story about three boys who are at summer camp and soon notice that very strange and unexpected things are happening near the camp. And like proper boys, they decide to get to the bottom of all these mysterious puzzles. After a series of adventures and comical misunderstandings, the story's dénouement reveals that the boys have helped expose smugglers who are bringing refugees from the East across the nearby border and robbing them of their meager resources.

The fairy tale is based on two fairy tales by Božena Němcová, "Righteous Bohumil" and "The Black Princess". It tells the story of a weak king and his wife, whose desire for a child leads her to a conspiracy with the devil. The princess, who grows up under the influence of the "impure" powers, only escapes from their power thanks to her love for the fisherman Radek.

A young woman named Alena discovers her fiancé Pavel's repeated infidelity. After meeting with her former married boyfriend, she loses control of her car and crashes. The result is tragic: severe injuries to her head, spinal cord, and spine. Even after several months, doctors and parents consider her condition hopeless. The only ones who do not lose faith in her recovery are the doctor in the rehabilitation department and her grandmother, who takes care of her. The others cannot cope psychologically with the situation that has changed their lives. Hopelessness and helplessness influence their actions. Will they be able to find the strength to overcome their selfishness and help not only Alena but also themselves?
