こおろぎ (2006)

Kaoru, a wealthy woman whose youth is fading, abandons the hustle and bustle of the city to live peacefully in a home on the coast. There, she takes care of an old deaf, dumb and blind man as if he were an insect, a child or a pet. He can’t do anything for himself, so she feeds him and accompanies him on his walks. This strong mutual dependency offers Kaoru an escape from society and allows her to free herself from restrictions imposed by common sense.
