Daigo Nagashima (Hiroshi Tachi) is about to retire from his company. He has a wife named Aya (Atsuko Asano) and his children are already married.

One day, Aya tells Daigo that she wants to open a "house restaurant," which she has dreamed about for a long time. This throws a curve into Daigo's plans to live peacefully after retirement, but he decides to support Aya's dream.

Now, their house restaurant is set to open soon. Younger people, who each have their own stories, come to the restaurant to work. While Daigo talks to these younger people, he realizes how important the family is. When Daigo and Aya raised their own kids, Aya was the only one to take care of the children.
