A boy comes home from school and reluctantly starts doing his homework. Suddenly, a large blot appears on the book's page. Grandpa Bibliophile comes out, orders the book to be cleaned, and shrinks the boy to microscopic size. The boy falls into the abyss and enters the world of letters. He meets Curiosity, who explains to him the meaning of words and their mutual relations. First, he comes to the word "beach," then to the word "winter," and finally to the word "garden." Curiosity promises the boy further extraordinary journeys.
