When the villagers of Klineschloss start dying of blood loss, the town fathers suspect a resurgence of vampirism. While police inspector Karl remains skeptical, scientist Dr. von Niemann cares for the vampire's victims one by one, and suspicion falls on simple-minded Herman Gleib because of his fondness for bats. A blood-thirsty mob hounds Gleib to his death, but the vampire attacks don't stop. 　　译文(2): 当 Klineschloss 的村民开始死于失血，镇长怀疑吸血鬼的复苏。虽然警督卡尔仍然持怀疑态度，科学家冯尼曼博士关心吸血鬼的受害者一个接一个，怀疑落在头脑简单的赫尔曼格莱布，因为他喜欢蝙蝠。一群嗜血的暴徒追杀格莱布，但吸血鬼的袭击并没有停止。
