He brings the animal home to his twelve year old son, Rabi, who becomes so fascinated that he forgets his chores at this father's shop. When the angry smith removes the tortoise, Rabi's grandfather, Pusga, helps Rabi find a larger one to consol the boy. Rabi wants to tame the animal and this new obsession leads him to defy parental authority. Pusga gently opens the boy's eyes to the visible and invisible ways of nature. Rabi starts to understand liberty, responsibility and respect for life. In turn he awakens long buried sentiments in the grandfather.
