Rich oddball Frederick Loren (Vincent Price) has a proposal for
five guests at a possibly haunted mansion: Show up, survive a night
filled with scares and receive $10,000 each. The guest of honor is
Loren's estranged wife, Annabelle (Carol Ohmart), who, with her secret
lover, Dr. Trent (Alan Marshal), has concocted her
own scheme to scare Loren's associate, Nora Manning (Carolyn Craig),
into shooting the potentially crazy millionaire. But more spooks and
shocks throw a wrench into the plan.
