The evil wizard Black Whirlwind steals the herd of a shepherd boy named Andriesh along with his faithful dog Lupar. Andriesh sets off to rescue them. On the way, he receives a magical flute as a gift, which helps him find his way to the wizard's castle — and comes to the aid of Black Whirlwind's numerous victims, who have long suffered from the tyrant's misdeeds. Based on a Moldovan fairy tale by Emilian Bukov.
