[Machine Translation] Set in a declining regional city, this coming-of-age ensemble drama depicts the story of one summer in the lives of a group of young people with difficulties in life, including interactions with technical interns, superimposed on the ecology of alien species such as the American catfish. Tatsuo is reunited with his old friend Tetsuya at the graveside of a friend who died in junior high school, and he and Yui, a former co-worker at his part-time job, spend a few days during their summer vacation in a local country town. While interacting with the Vietnamese technical intern trainees they meet there, they gradually come to face the past that each of them has been dealing with. The main character, Tatsuo, is played by Nakayama Yuto of "Morning Comes, It's Meaningless" and "Coco de Hanashi" fame. The heroine Yui is played by Yura Kikino of "Goodbye, Bad Magazines" and "My Moon is Kittanai. Ayumu Matsuyama of "Hippo" and "When April Comes" plays Tatsuo's junior high school classmate, Tetsuya. The role of Shinichi, Tatsuo's father, is played by Hidetoshi Kawaya (Reiko Iruka), and the role of Watanabe, who works at Shinichi's factory, is played by Hirofumi Watanabe, who also works as a film director with the film production group Otawara Gyubutosha. The supporting cast includes Tatsuhiro Yamaoka (The Red Post on Escher Street) and Yota Kawase (Rage, Hakon Otoko). Directed by Kyuya Nakagawa of "A Ku-A -A Room Just for Two". Screenplay by Etsuro Hiratani of "Fumiko's Feet" and "Umibe no Shojo". The theme song is "At the riverside" written by singer-songwriter Saho Terao for this film. Her voice, which accompanies them as they earnestly live their lives, leaves a deep aftertaste. A masterpiece depicting the 2020's is born, reflecting Japan's lack of hope for the future! Includes a booklet (16 pages).
