Dr. Bela Reinhardt (Ron Chaney) is a mad doctor who has invited five people to his castle to determine which of them shall inherit his estate. He has arranged for a competition of sorts. The winner will be chosen by process of... elimination. The visitors quickly realize they made a terrible mistake in accepting Reinhardt's invitation, but are trapped like rats in a cage under the watchful eye of Reinhardt's ghoulish manservant, Barlow. They soon discover the castle is full of terrifying monsters such as the Wolf Man, Frankenstein's Monster, and Dracula.
Infinite Hollywood reviewed the film for Halloween 2011, "This movie is such a good concept, horribly wasted. The dialogue isn't so badly written (with a few notable exceptions), but spoken by these stiffs it comes across horribly".
