When Mama forbids her little son, who is called Father Fyodor by everyone due to his mental maturity, from having a pet, Fyodor decides to move out. Together with a cat and a dog, he lives undisturbed in an empty house until the clever village postman takes the parents' missing person report very seriously. But until then, the cat, dog, and Fyodor practice independent living. And they succeed remarkably well.
