In 1984, young guitarist
Euronymous forms
black metal band
Mayhem, the first of the genre in their country of Norway, with
Necrobutcher on bass and
Manheim on drums. Manheim leaves and is soon replaced by new drummer
Hellhammer, and they recruit a vocalist from Sweden called
Dead. Dead exhibits
self-destructive behavior; during their live shows,
he cuts himself, bleeds on the audience, and throws pig heads at the "
posers". At a show filmed by their friend Metalion, the band meets a timid fan named Kristian, whom Euronymous initially undermines and patronizes. Euronymous also meets Ann-Marit, a girl from the metal community, and is instantly attracted to her. While home alone, Dead slits his wrists and throat with a knife, then uses Euronymous' shotgun to
shoot himself in the forehead, leaving behind a
suicide note. Euronymous returns to find Dead's body; instead of calling the police, he repositions and takes photos of the corpse. After Dead's body is taken to the morgue, Euronymous makes necklaces out of pieces of Dead's skull and gives them to the other members. Horrified and disgusted at Euronymous' flippant response to their friend's death, Necrobutcher leaves the band. Soon after, Euronymous starts his own
black metal record label and opens a record shop called
Helvete ("Hell"), which becomes a social hub for black metal fans, including Kristian, who is now calling himself
Varg Vikernes. They become known as the "Black Circle". After being mocked by Euronymous, Varg burns down a local church. When challenged by Varg regarding his status as the leader of the Black Circle, Euronymous burns down a church with
Faust and Varg accompanying. Not long after, Ann-Marit and Euronymous enter a relationship. Euronymous recruits Varg as bassist, along with a guitarist called Blackthorn and Hungarian vocalist
Attila Csihar, to record Mayhem's first album,
De Mysteriis Dom Sathanas. A power struggle between Varg and Euronymous soon arises. After a wave of church burnings and the
murder of a gay man by Faust, police begin to link members of the local black metal scene to the crimes, sending Euronymous into
paranoia. Helvete is shut down, and Varg is arrested as prime suspect after an interview with a Bergen newspaper in which he boasts about his responsibility for the crimes, though he is soon released due to a lack of evidence. Afterwards, Varg tells Euronymous that he is leaving Mayhem with plans to start his own record label. In the ensuing conversation, Euronymous admits that the skull piece necklaces were fake and that his violent, anti-authority mindset is merely a persona he adopted for the sake of promoting the band, which angers Varg. While packing up the shop, Euronymous angrily rants to a peer about Varg, blaming Varg for the deterioration of the black metal community and expressing a desire to kill him in retaliation. After taking advice from Ann-Marit, Euronymous calms down, sends Varg a contract releasing
Burzum's music rights to him, and decides to continue with Mayhem. When Varg hears of Euronymous' death threats, he travels to Oslo to confront him. He convinces Euronymous to let him enter the apartment by stating he wants to sign the contract. However, once inside, Varg stabs him after a brief conversation. Varg chases Euronymous to the stairwell outside, where he stabs him to death, ignoring him as he pleads for his life. News of Euronymous' murder spreads throughout Norway and Varg is soon arrested. He is convicted of both the murder of Euronymous and the burning of several churches and sentenced to a maximum of 21 years in prison. In a
voice-over, Euronymous tells the audience not to mourn his death, as he lived a successful life and accomplished many things. ==Cast==
