Nello Tarth is a poor but happy orphan who lives with his grandfather Jehan in a little village nearby Antwerp. Nello has a talent for drawing pictures and has been fascinated by it since he saw one of Rubens (a famous artist) pictures as a little boy. Helping Jehan with the daily milk delivery to Antwerp, Nello one day discovers Patrash, a working dog who has been mistreated and abandoned by his former owner. He treats the exhausted animal and after a little while a close and dependable friendship develops.
