Billy Shake is an American rock star of epic proportions. So beloved throughout the world that the devil himself, known here as Dr. Spark, brings Billy to Hell to entertain him and his followers. Dr. Spark also wants to perform alongside him to nurture his own ego and try to convince Billy that he could have anything he wants if he stays.
Billy sings songs for the inferno but fights to retain and express his belief in the love of God, country, and the pursuit of love. Dr. Spark, with the help of his singing sodality, the Demonettes, taunt and mock Billy and all he stands for in the hopes of leading him astray.
