The film is a mockumentary that follows a fictional British heavy metal band as they embark on a tour across the United States. In an attempt to revive their waning popularity, the members face a series of comedic mishaps and obstacles that highlight their declining relevance in the music scene. The band deals with everything from technical malfunctions and a shrinking fan base to the peculiar demands of their eccentric members. Through interviews, concert footage, and candid moments on the road, the documentary-style approach provides a humorous look at the pitfalls of rock stardom and the quirks of the music industry.

As the tour progresses, internal tensions and external pressures begin to take their toll on the band members and their entourage. The filmmaker, aiming to capture the essence of the band's legacy, inadvertently documents the strains and absurdities that come with fading fame and fortune in the rock world. Miscommunications with event organizers, bizarre performance incidents, and creative disagreements underscore the challenges faced by a group trying to navigate their past glory and present reality. The film cleverly satirizes the world of rock music, poking fun at both documentary filmmaking and the often ludicrous nature of the rock 'n' roll lifestyle.
