A remarkable meeting of two completely different beings - not only in age, but also in social and social class - takes place in one day. Zuzanka is a nine-year-old girl who, thanks to her mother's premature departure for the maternity ward, finds herself alone in the apartment of an old tenement house, while Zdenka is the slightly spoiled wife of a successful businessman for whom almost nothing is unattainable. Except for one thing - the ability to have a pure, primary view of the world and a spontaneous reaction to it. What can these two such disparate people give (or even take?) from each other - that's what this present-day story is about.
