In a rural town in Saitama Prefecture, Hiroshi Tanaka (Shota Matsuda), who has a super exaggerated afro, spent his childhood, adolescence and youth in a muddle. After dropping out of high school on his own initiative, he said goodbye to his best friends Osawa (Atsushi Tsushita), Okamoto (Kei Tanaka), Inoue (Ryusuke Komagone) and Murata (Kaname Endo), and went to the metropolis of Tokyo to make a living. Tanaka, who works for a tunnel excavation company, worked day after day and unknowingly ushered in his 24th birthday. One day he received an invitation to Inoue's wedding, and then he remembered the agreement he made with his friends: no matter who gets married in the future, everyone else must bring their girlfriends to attend. Seeing his friends and their ordinary or beautiful girlfriends going out in pairs, being affectionate with each other, Tanaka was extremely anxious. At this moment, the beautiful and gentle female neighbor Kato Aya (Nozomi Sasaki) appeared in front of him, which ignited the hope of love for the useless Tanaka... This film is adapted from "Kamikyo Tanaka" in the popular series of comics "Afro Tanaka" by cartoonist Noritsuke Masaharu (Noritsuke Masaharu).
