Set against the grim, snow-drenched landscape of early 1990s Norway, this chilling biographical drama dives into the true story of the most notorious spate of crimes in heavy metal history. The film follows Rory Culkin as Euronymous, the fiercely ambitious founder of the black metal band Mayhem, who dreams of creating a new, violently authentic musical genre. He recruits the volatile Emory Cohen as the band's charismatic but deeply troubled frontman, Pelle "Dead" Ohlin, and the two form a dark symbiosis fueled by nihilism and a desire for infamy. As their music gains a cult following, a new rival emerges in Jack Kilmer as the manipulative Count Grishnackh, whose own extremist ideology pushes the scene toward escalating acts of arson and violence. Directed by Jonas Akerlund, the film captures the claustrophobic intensity of a subculture spiraling out of control, blending brutal horror with a stark biographical account of ambition, madness, and the destructive pursuit of artistic purity.
