What is the plot of the authority movie?

Nirvanna the Band the Show the Movie is a 2025 Canadian comedy directed by Matt Johnson and co‑written with Jay McCarrol. The film adapts the humor of their 2007–2009 web series and 2017–2018 TV adaptation, bringing the duo back to their own lives as they try to secure a performance at the Rivoli nightclub in Toronto. In the story, a plan they concoct to secure the gig inadvertently transports them back in time to 2008, setting up a comedic exploration of their past and the music scene of that era. The narrative blends the duo’s self‑referential comedy with a time‑travel twist, examining the challenges of booking a show and the impact of early‑career decisions. The film is produced in a guerrilla style over 200 days with a small crew, mirroring the spontaneous feel of the original series.
