Owners of all kinds of animals and birds, from puppies to sick calves and grasshoppers, come to the veterinary "hospital". They meet with the professionalism and helpfulness of the doctors and especially with the attending nurse Miluska, who finds a kind caress, a smile and help for every creature. She even gets the doctor to visit a sick grasshopper, which its rather stubborn owner left without treatment. There's a bit of loving reverie on Milushka's part, too, because she liked the young man who came with the mare. But it remained just a nice, if a bit silly dream, because the young man is married. But the daily reality overcomes that bit of sadness and Milushka remains faithful to her patients...

Third part of the trilogy. Vaska again is visiting his grandfather living in Bohemian Forest and understands the importance of guarding nature.
