"What is a wish?" That is the question the boy must answer for himself as he and his wolf, Cloud, embark on a grand voyage to find the boy's father and return the wish that was stolen from him. The Cloud is a beautiful, and at times, heartbreaking journey of a reluctant hero forced to outwit a cast of colorful characters: a thieving girl, bizarre creatures from the Great Before, and the Mad King. It's a quest of self-discovery where the boy will learn that not all wishes can or should come true.
