Tanya, a 10-year-old Russian tourist traveling with her parents from Prague to Brno, is left behind in a foreign country. Tanya leaves her compartment when the train stops because of a cow. Disobeying her parent's instructions, she gets off the train to investigate, lingers too long, and is left behind. Cold, lonely, and clad only in her pajamas in the unfamiliar countryside, the girl is relieved to meet up with two rather nervous Czech boys camping out together for the first time. At first the would-be "cowboys" are frightened by her ghost-like appearance. After hearing her story, the boys find Tanya a dress to wear and accompany the girl on foot to her final destination, Brno.

Created by Czech director and animator Zdeněk Miler in 1956, Krtek, or The Mole in English, was an international hit with children. Because the cartoons were presented with no dialogue, Krtek was held to no national boundaries.

Milers daughter voiced the noises and grunts that Krtek made, and gave Miler the feedback from a child's perspective he needed to keep his stories focus on his young fans.

You will meet the family of the miller Kaliba, who is proud not only of his mill, but also of the family tradition, according to which the milling profession has been passed down at the inn's mill for almost three hundred years. And since Mr. Kaliba has no son, it is certain that his only daughter Liduška must marry a miller. Perhaps this would have happened if the Kalibas had not gone to the anniversary exhibition. Here, Liduška meets the handsome engineer Karel Loukota, who is an overly zealous member of the cycling club "Don't Get Married!", but is not immune to love at all. Of course, he will face many hardships and obstacles, the biggest of which is, of course, the miller Kaliba with his fierce efforts to uphold the family tradition...

Even the pre-Blohemian times were not idyllic. Even a bachelor, invited by the consuls to Rakovník to elevate the local education system, finds out. But the stingy and proud townspeople soon grow to dislike him, and even love does not develop according to his wishes.
