On a faraway mountain live the Krots, a people who know the secret of taming clouds. Admiring their powers, a boy named Petar becomes their pupil. Soon, however, he realizes that he can only become a cloud tamer if he relinquishes all emotions. If he succeeds, he will become a true tamer—glorious, cold and superior. However, here is Cloudlet, his little friend who has taken over Petar's voice and does not stop speaking to him about feelings. While Petar battles with himself, the Krots, and the clouds, something that would change him completely happens... For the first time he makes the acquaintance of the feeling known as love.
