In this horror chiller, an intriguing, beautiful woman (Sandra Knight) keeps re-appearing to early 19th-century Lt. Duvalier (Jack Nicholson), and he is led to a castle where he finds an imposter of Baron Von Leppe (Boris Karloff). He becomes trapped in the ancient castle and tries to make sense of the eerie situation. Director Roger Corman (with the help of a few other directors, including Francis Ford Coppola) shot most of this within a few days after finishing The Raven--utilizing the same set.
