The universal theme of friendship, in all its vulnerability, tenderness, and purity, is explored in this drama. The flow of seasons forms a thematic continuity to the action: the severity of youth in summer, the sentimentality of autumn, and the frustration of winter. Together, this group of boys cope with common adversity, face the death of a friend, and prepare to deal with the world of adulthood.
