Claudia is a self-confident girl who spends time in a Young Pioneer camp and wants to prove that she can keep up with the boys in a scouting wide game.

Little Nelli is a clever and cunning child. As her parents are both working, her grandmother has to care for her. But her grandmother is no match to Nelly. Out on the street, Nelli also calls the tune and becomes the kids’ favourite with her brash pranks. But when Nelli enters day nursery, the situation changes completely. Suddenly, Nelli is no longer at the centre of attention and starts to upset the group with her aggressive stubbornness and to revolt against the rules.
