Left homeless and stranded, Seita and Setsuko wander the countryside, battling hunger and sickness. Despite encountering apathy and occasional cruelty from those around them, their unyielding optimism in the face of overwhelming hardship sustains them, temporarily delaying the inevitable conclusion of their tragic journey.
