The final chapter of director Mukai Hiroshi's trilogy on the theme of aging, in which "Going West" raised the issue of human memory and "Hometown" addressed the issue of the physical strength of the elderly. "Class Reunion" depicts the "gathering" that fills the feeling of loneliness in daily life. A man who left Japan for a foreign country during the chaos of the post-war period returns home for the first time in 60 years to spend the rest of his life in Japan, embarking on a journey with his former best friend to recapture the days of his youth.
