On the eve of St. Sound's Sunday, the holiest day of the year, the nun's of Cedar Monastery work tirelessly overnight to prepare for the next day's Mass. While trying to find a broom to clean the rafters, the newest nun, Jazz, is met with divine intervention.
She hears the voice of God for the first time. He bestows upon Jazz his will and graces her with his enlightenment. His will being that she must kill a demon in the monastery. And his enlightenment being a 12 gauge double-barrel.
Scared out of her mind, Jazz investigates the monastery to figure out just where this demon could be. Or who it could be.
