About
Aki, the young daughter of the Iwatas, disappeared five years ago. They still distribute missing person fliers every week. The husband, Masayuki, would like to move on with their life, and is sad that their marriage has cooled off. The wife, Ryoko, spends her time drinking, writing Aki's name on school notebooks and taking care of a school backpack that they never got to use. One day, the Iwatas are approached by a pregnant young woman called Rina, who wants to help them distribute fliers. Ryoko quickly gravitates towards a friendship with Rina, as if to fill a hole in her heart.
