An entomologist on vacation is trapped by local villagers into living with a woman whose life task is shoveling sand for them.
Jumpei Niki, a Tokyo based entomologist and educator, is in a poor seaside village collecting specimens of sand insects. As it is late in the day and as he has missed the last bus back to the city, some of the local villagers suggest that he spend the night there, they offering to find him a place to stay.
