The children's detective story describes a thrilling and cheerful search for a lynx that someone stole from the zoo corner of the house of pioneers and young people (the creators apparently assume that large carnivores are commonly bred in the children's facility). However, the film is made completely ingeniously, the naïve plots hardly catch the eye. In one of the last roles, Vladimír Menšík will introduce himself as a police captain, leading a long-complicated investigation
