Long before lunatic millionaires Michael Jackson, Richard Branson or Rick Rockwell, there was Frederic Loren (Vincent Price), an eccentric, unhappily married fop who offers a huge cash prize to anyone who can stay overnight in the house on Haunted Hill (the house, by sheer coincidence having nothing whatsoever to do with its location on a haunted hill, is haunted). The guests have to contend with hauntings, a sparsely stocked bar, and a huge cistern filled to brimming with flesh dissolving acid (the previous owner evidently tired of hauling his excess flesh to commercial flesh dissolving operations.) The film's many twists and turns will keep you guessing! (How many twists and turns? Well, say, two twists and maybe one turn, if you want to be generous about it.)
Mike, Bill and Kevin take up his offer, pack their Star Wars sleeping bags and spend a wild night in the House on Haunted Hill.
