A son carries his mother up a mountain to abandon her because the lord demands it. The animation moves like watercolor washing across silk, each frame justifying itself before the next one arrives. This is what happens when a studio trusts silence and painting over dialogue: a story about why old people matter becomes undeniable, not because it argues the point, but because you watch a man's hands shake while he ties her to a tree. The feudal lord learns what he destroyed. You learn it first, through the motion of ink and the weight of what is not said.

A young man faces an impossible choice when the cruel lord of Shinano Province decrees that the elderly must be cast out to die. His mother has reached that age, but he loves her too much to hand her over to the officers. After carrying her toward the mountain, he cannot go through with it and hides her beneath the floor of a barn instead. When a neighboring lord sends impossible challenges backed by threats of force, the son quietly turns to his mother for answers. Her wisdom saves the province and shows the lord what he has been throwing away. A short folktale film about duty, compassion, and honoring the old.
