It's a Hard Day's Night in Japan with a Faustian twist. The Screamin' Telstars are a Japanese retro-rock band fronted by Tony on lead vocals and lead guitar. They have been struggling and playing together for years but have never met with any real commercial success. One day, Tony's amp burns up and he goes to buy a new one at a guitar shop with a curious owner. Tony winds up with an amp with a history. From the amp emerges a ghost who promises Tony fame and immortality in return for a favor: getting rid of his band forever. The ghost also promises Tony fame greater than his old rival from his student days: rock god Shinzo. Tony gets everything he ever dreamed of--but not exactly the way he planned.
