Synopsis: The grotesque and sinister mansion of the late Cyrus West has stood empty for twenty years - until tonight. On this stormy evening, the eccentric millionaire's will is to be read, and his greedy potential heirs gather in the cobwebbed halls of the foreboding gothic manor. Cyrus' disdain for his money-hungry relatives is evident when he bequeaths his fortune to his most distant relation, the lovely Annabelle West. But Cyrus has placed an unusual clause in his will. Annabelle must be proven to be sane in order for her to collect the money and, if she is not, the untold wealth will go to another heir whose name remains sealed in an envelope.
