Monster Panic: Strange Tactics

Aliens from the dying world of Ummo plot to conquer Earth by preying on man's superstitions. To preserve the Earth's health for their subsequent use, they want to avoid nuclear devices. They bring two dead scientists back to life, controlling their bodies - surgeon Kierian Donner and biochemist Maleva Kerstein. Then, they use their advanced scientific technology to set up an elaborate laboratory facility in an old monastery to re-animate various monsters, including a werewolf (Waldemar Daninsky), Ulrich Von Farancksalan's monster, the mummy Tao Tet, and a vampire Count de Meirhoff. The aliens do not credit the depth of passion of the scientists, whose bodies they occupy, leaking through. The woman in particular first falls under the hypnotic spell of the Count, but eventually is totally smitten by Kierian. As so many people end up dead or missing, the local law authorities send in Inspector Tobermann to investigate. HIs supervisor thinks he is demented in talking about vampire and werewolves. His persistence, however, leads him to Ilsa Stranberg, who gives a first-person account of escaping a werewolf. Her father, an influential judge, personally knew one in the past. Tobermann is able to penetrate the alien's stronghold inside an old monastery and turn the tide against the invaders. He takes out the vampire. The werewolf, who has fallen in love with an enslaved human, does the monster and the mummy in. The alien base eventually blows up.
