A community is shocked when the bodies of an elderly man and the manager of a home-visit nursing centre are found. The passing of 42 elderly patients is connected to Shiba, a caretaker recognised for his affection and dedication.

A man is immobile and incapacitated, but has professional and nonprofessional volunteers serve and help him. Though, he takes full advantage of the situation and uses and abuses the volunteer crew.

Too shy to speak out the word of appreciation, too busy to show that you care... Many excuses lie between each and every couple, when they look back the distance created during the long years in which they took each other for granted... Love Letters sent from husbands to wives and from wives to husbands, quietly voice their unspoken appreciation for each other over the years that they have shared. The original idea comes from the postcard project "Love Letters at Sixty" which has brought a wave of sympathy to the precious emotions shared by many married couples.
