House on Haunted Hill

Rich oddball Frederick Loren 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, who, with her secret lover, Dr. Trent, has concocted her own scheme to scare Loren's associate, Nora Manning, into shooting the potentially crazy millionaire. However, more spooks and shocks throw a wrench into the plan.
