Oslo, 1987: Seventeen-year-old Euronymous (Rory Culkin) 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 (Jack Kilmer) and Varg (Emory Cohen). 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
throughout the countryside and stealing tombstones for their record store.
But when the press catches up with them and Euronymous takes more credit
than he's earned for the group's violent acts, Varg, fresh out of jail,
arranges a dark encounter to settle the score and ultimately determine who
the darkest black metal musician is...
