The story of True Norwegian Black Metal and its most notorious practitioners: a group of young men with a flair for publicity, church-burning and murder: MAYHEM. Oslo, 1987, Seventeen-year-old Euronymous is determined to escape his idyllic Scandinavian hometown and create “true Norwegian black metal” with his band, MAYHEM. He’s joined by equally fanatical youths - Dead and Varg. Believing that they’re on the cusp of a musical revolution, the group gets even darker driven by the black metal dogma to spread evil. They begin burning down churches and stealing tombstones for their record store. But when the express catches up with them and Euronymous takes more credit than he’s earned for the groups violent acts, Varg, fresh out of jail, arranges for a dark encounter to settle the score and ultimately determine who the darkest black metal musician is.
