Aspiring heavy metal band, Rage of Angels, have found a perfect place to practice their music: an abandoned church in Spirit Lake, Idaho.

But once they set up their gear on the vacant altar, a barrage of eerie occurrences threaten to drive the band out of their new sanctuary.

When they discover that the church is haunted by enraged ghosts of the Kootenai Indian tribe, they utilize the advice of a voodoo priestess to confront the angry spirits.
