It is Sportsday in a small mountain school in Japan. Children compete in races and the principal awards prizes.
Parents come carrying lunch boxes and kettles of tea, to cheer the children on.
The last event is almost over. The playground suddenly becomes quiet as two strangers, American soldiers, appear at the gate. The children have never seen American soldiers and are at first afraid and shy, until the two wave and smile. Then one soldier begins to ride the principal's bicycle. At first the children giggle, but then the tall stranger performs amazing feats, each one more daring and magnificent than the one before.
