For four decades, the punk rock band NOFX has built a legendary, chaotic, and deeply contradictory legacy onstage and off. Directed by James Buddy Day, this raw and unflinching musical documentary chronicles the band's journey from Los Angeles skate-punk misfits to unlikely elder statesmen of the genre, all while seemingly trying to sabotage themselves at every turn. At the heart of the story are the band's core members—frontman Fat Mike, guitarist El Hefe, bassist Eric Melvin, and drummer Erik Sandin—whose turbulent brotherhood and personal demons are laid bare. As they navigate the milestone of their 40th anniversary, the film captures the tension between celebrating a improbable survival and confronting the painful costs of a life lived in relentless, rebellious excess. Filled with blistering live performances, brutally honest interviews, and a treasure trove of archival chaos, the film delivers a portrait that is as hilarious as it is heartbreaking, exploring whether a band founded on "fuckin' up" can finally grow up.
