With amusing illustrations and child-friendly language, the book shows the ideal world of Mr Peppers, a modest self-sufficient farmer who lives in harmony with nature in the countryside, as well as the hardships that this traditional way of life without electricity and modern resources entails. The humanised young broom Bobby, who has little arms and can speak, is his best friend. In the course of the story, Professor Rashly appears as a counterpart who, driven by quick fame and greed for attention, thoughtlessly invents useless things and uses his modern knowledge inappropriately.

Without pointing fingers or heavy-handed punishment, the professor is ultimately persuaded to change his mind. The reason for his change of heart is provided by Mr Peppers and a special natural product. Thanks to their new friendship, Professor Rashly increasingly learns to appreciate the benefits of nature and to use his inquiring mind with care. In return, the professor teaches Mr Peppers about the benefits of science and technology, which, in an environmentally conscious and well-measured way, will make his everyday life easier.
