A step away from losing her job, record company employee Kanna comes across an awesome punk rock band called Shonen Merikensack on the Internet, and sets out to sign them. With her job on the line, she discovers too late that the video she saw is actually an old clip from the 80s, and the members - bassist Akio, guitarist Haruo, drummer Young, and vocalist Jimmy - are now all down-on-luck middle-aged fogies. As buzz for the mystery band grows, Kanna's record company, still in the dark about the truth, decide to launch a concert tour for Shonen Merikensack, and they want Kanna to be the band's manager!
