 Amina loves Rudolph and turns the powerful Count Wolfenstein down when he proposes to her. In a jealous rage, Wolfenstein throws Rudolph into a dungeon. Meanwhile, Hertzog, "The Black Crook," has a deal with the devil: he must hand over to Satan one soul each year or find himself banished to Hell. With only 24 hours left before the year ends, Hertzog focuses all of his attention on Amina and Rudolph, believing them to be weakened from despair and therefore easy prey.
