This documentary takes a behind-the-scenes look at the controversial Norwegian black metal scene of the 1990s, an idealistic and innovative musical movement marred by jealous infighting and an unfortunate campaign of public violence. Drummer Leif Gylve "Fenriz" Nagell of Darkthrone and Varg Vikernes of Mayhem -- an innovative but troubled musician who spent over a decade behind bars for the murder of black-metal guitarist Øystein "Euronymous" Aarseth -- tell their stories.
