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.
