The Ultimate Vampire Resource and Directory

Set in 1961, the film begins with hardworking scientist Dr. Paul Armstrong (Larry Blamire) and his dedicated wife Betty (Fay Masterson) driving into the mountains. Dr. Armstrong is searching for a meteor that has fallen in the nearby woods, suspected to contain the rare element atmosphereum. Another scientist in the area, Dr. Roger Fleming (Brian Howe) questions Ranger Brad (Dan Conroy) about Cadavra Cave, a site held in awe by the locals and rumored to contain a "Lost Skeleton."

In the evening, both the Armstrongs and Dr. Fleming observe in the sky another falling meteor. An instant later, a farmer (Robert Deveau) encountered by the Armstrongs on their way to the cabin is horribly mutilated by a mysterious beast. The second meteor is, in reality, a pair of aliens in a spaceship. Kro-Bar (Andrew Parks) and Lattis (Susan McConnell) are from the planet Marva and are stranded on Earth, in need of the element atmosphereum to repair their powerless ship. The ship's pet mutant (Darren Reed) escapes from its cage while they are distracted.

The next day, Dr. Roger Fleming finds and enters Cadavra Cave, at last locating the Lost Skeleton. The Skeleton commands Fleming to locate atmosphereum to return him to life. Meanwhile, Dr. Armstrong and Betty adventure into the woods, finally discovering the meteor just outside Cadavra Cave. Dr. Fleming overhears them, and begins to plot to steal the meteor from the pair....
