Dylan, Jordy, and Spud, a trio of outcasts in a struggling heavy metal band called Dethkrunch, decide to capitalize on the town's sudden interest in the occult by rebranding themselves as a Satanic metal band. This leads to them becoming the targets of the town's witch hunt, especially when a bizarre series of murders, kidnappings, and reported supernatural activity begins happening.
