Heavy Metal Horror follows a day in the life of Julia, a prostitute constantly shadowed by an unseen, supernatural presence. Hounded by her pimp, a shifty lowlife named Vincent, Julia has finally reached her breaking point. She escapes Vincent’s grasp, and finds herself in the company of an unlikely group of protectors: a heavy metal band named Armifera. Fronted by the drug-addicted but charismatic Damian, the band takes her in after one of their concerts for a night of excess. What Julia doesn’t realize however, is that the band has something planned for that night, something dark, and it’s only a matter of time before their worlds collide with terrifying results.
