Four years ago the Endou family decided to move to Hibarigaoka even though it was beyond their means. Building a small house was the dream of the mother, Mayumi. But the neighbourhood is everything but welcoming to the new family as they are seen as a threat to the standard of the neighbourhood. However the Takahashi family, especially the mother Junko, finds a friend in the Endou family and start acquainting with them. Still, not everything is as it seems on the surface. One day Hiroyuki Takahashi is murdered and the police suspect the crime was committed by someone he knew.
