In the 19th Century Austrian village of Stettel, children are mysteriously disappearing. The villagers realize that the villain is the local count. Summoning their courage—attacking a nobleman is punishable by death—they charge into his castle, where they discover the dead body of a little girl and the very much alive body of Anna, a school teacher's wife who is now the count's lover. The count is a vampire, so the villagers dispatch him with a stake through the heart. But with his undying breath, he swears vengeance: that the villagers and their children will all suffer and die so that he can return. Fifteen years later, the village is quarantined due to a plague. No one can enter or leave, and there are guards at the perimeter. But somehow, a circus makes it through—a bizarre circus that both entertains and terrifies the villagers. But the Circus of Nights is no ordinary circus—it's a Vampire Circus, here in Stettel to avenge the evil count.
