A boy returns to his family home in the country and strikes up an
odd friendship with the young child who lives next door, Sora-san, who
believes he is God. However, it is Plato, the boy's pet turtle, with
whom Sora develops a strong bond. Plato believes Sora to be the
classical Greek philosopher Socrates and calls her his teacher.
Together, they ponder the mysteries and wonders of life in the quiet but
beautiful countryside.
