在这部吸血鬼也疯狂喜剧/惊悚片中,1893年，英国律师托马斯（彼特•麦尼科 Peter MacNicol 饰）奔赴特兰西瓦尼亚，在当地居民的惊恐中拜见了德古拉伯爵（莱斯利•尼尔森 Leslie Nielsen 饰），并为其代理购买了一座英国修道院。德古拉次日将托马斯蛊惑，使其变成了自己的忠仆。主仆两人来到英国伦敦，德古拉见到了修道院左近精神病院的管理者斯沃德医生，斯沃德医生女儿的美丽朋友露西令德古拉心怀吸血念头，同时，托马斯因为吞食昆虫被斯沃德医生控制在精神病院中失去自由。德古拉吸食露西血液得逞，后者陷入昏迷，焦急的斯沃德医生请来医学院教授范海辛（梅尔•布鲁克斯 Mel Brooks 饰）相助，才知道吸血鬼来袭的真相。范海辛率众人与德古拉及其仆人展开了一场拉锯式的吸血攻防战……
Another spoof from the mind of Mel Brooks. This time he's out to poke fun at the Dracula myth. Basically, he took "Bram Stoker's Dracula," gave it a new cast and a new script and made a big joke out of it. The usual, rich English are attacked by Dracula and Dr. Van Helsing is brought in to save the day.
