A former principle (Nagatoshi Sakamoto) lives in a shut down elementary school. The ex-principle lives peacefully there, while repairing the old school. One day, a decision to dismantle the school is made.

Noda (Hidetoshi Nishijima), a former student at the elementary school, comes back to town to work as a museum employee. He visits his former school to retrieve articles housed in the school. Noda also has a small secret about a time capsule buried at the school. The time capsule was buried during the last day for the school.

Noda meets his former principle and also former teacher Ayako and her daughter Ritsuko (Chieko Baisho). While seeing them, Noda's memories of his school days come back. Ayako lived in a nursing home, but she is being moved to a large hospital in the next town. With her daughter helping her to move, she stops at her old school.
