Hunter Sylvester is an abrasive, obsessive high school metalhead obsessed with forming a band called SkullFucker with his socially awkward, timid best friend, Kevin Schlieb, whom he recruits to play the drums. While Hunter is driven by deep-seated rage toward his affluent father and a desperate need to win the upcoming
Battle of the Bands, Kevin struggles with finding his own voice and confidence, initially joining simply to remain close to his domineering friend.As the duo prepares for the competition, Hunter forces Kevin to push his musical boundaries. However, the dynamic shifts drastically when Kevin witnesses Emily Spector, an intense and troubled cellist with severe emotional outbursts, violently destroying her cello after being rejected by the school orchestra. Intrigued and sympathetic, Kevin invites Emily to join their group as a rhythm guitarist and backing vocalist, hoping to elevate their heavy metal sound with classical precision.Emily quickly proves her musical genius, but Hunter immediately resents her inclusion. Driven by toxic gatekeeping, rigid genre purity, and intense misogyny, Hunter demands Emily conform to his extreme standards, leading to escalating friction. Emily battles her own demons, specifically her struggle with
bipolar disorder and the side effects of her mood-stabilizing medication, which dulls her creative spark. Despite Hunter’s hostility, Kevin and Emily grow closer, eventually developing a romantic connection that further alienates the jealous and controlling Hunter.The tension peaks when Hunter discovers that Kevin and Emily have been practicing without him, leading to a massive blowout. Feeling betrayed and abandoned, Hunter kicks Kevin out of the band and out of his house. Left isolated, Hunter spirals into self-destruction, nearly ruining his academic and personal life. Meanwhile, Kevin is forced to confront his codependency and muster the courage to stand up to Hunter for the first time.Realizing the error of his ways after a heart-to-heart with his estranged father and an honest reckoning with his own abusive behavior, Hunter reaches out to make amends. He reconciles with Kevin and accepts Emily as an equal bandmate. Having renamed their group Skullflower, the trio takes the stage at the Battle of the Bands. Instead of playing a generic metal cover, they perform a ferocious, original fusion of heavy metal and classical cello. Although they do not win the competition, the performance is a triumph of artistic expression and personal growth, cementing their bond and proving to Hunter that friendship and collaboration matter far more than gatekeeping and rage.
