Since childhood, we have known the fairy tale “The Little Humpbacked Horse” by P.P. Ershova. What happens if the plot of the fairy tale is moved to the north? For example, to Karelia? And instead of Ivanushka the Fool there will be a simple Karelian girl Ilma? By chance, she ends up serving in the royal court. What adventures does she have to embark on to carry out the orders of the capricious Queen and her cunning, envious chief caretaker! But Ilma’s assistant is not the Little Humpbacked Horse, but the magical fawn Onni. And he has his own secret! Only friendship, mutual assistance and loyalty will help friends overcome all obstacles and break the evil spell.
