Black metal vocalist Attila and his band 'The Black Rubric' are on tour, but their set has grown a little stale. Unbeknownst to the rest of the band (and even himself), Attila has been corrupted by dark forces, and when he pens a new song for them to play at their hometown show, all Hell breaks loose - literally.
Attila and the band must find a way to undo what they've done and send the demons back to Hell - writing satanic metal songs is cool and all, but how will they get any gigs if the rest of Quebec becomes a bottomless pit of molten sulphur?
