Although he is in management, he is not respected by his subordinates. His wife Sae (Tomoko Yamaguchi) is a popular food designer. She is busy with work every day and has no time to spare. The only daughter Moe (Ayame Maita) has a strange temper. She claims to have a sixth sense and often causes trouble at school. One day, Ryota's estranged father Eisuke (Isao Natsuyagi) fell ill on the way to Nagano.

It was a journey of discovery full of surprises and comfort, where many lost emotions and memories were restored unconsciously...
