The Invisible Dead

One rainy night, Dr. Garondet (F. Valladares) is summoned to the castle of Professor Orloff, but it is not an easy trip - local peasants won't direct him there, and when he finally locates a willing coachman, his horse refuses to venture beyond a certain point! Making it to the castle on foot, the good doctor encounters even more obstacles until he meets Cecile (Brigitte Carva), Orloff's daughter, a seemingly deranged girl who is convinced that an invisible phantom is at large on the premises. A surprisingly urbane man, Orloff (Howard Vernon) explains the story behind Cecille's insanity - a story involving premature burial, grave robbing and flagellation - but as Garondet spends an uneasy night at the castle, he finds himself sharing in Cecile's delusions...
