Fritz the little mouse has found out a secret! The old oak which is housing his family will
be cut down soon to make place for a new road. Alarmed Fritz's great-grandfather Balthazar
visits tree-spirit Big Cloud who is living in the Oak. Big Cloud asks the wise owl Lu for
advice. Lu who lives in the tree top is very upset about the planned devastation of their
environment and promises to help. Working together the tree spirits in the nearby forest and
the other animals who live near the Oak make up their mind to save the tree and prevent the
roadwork. Is there a chance for them?
