There are four college-age kids driving cross-country, researching a book on weird roadside attractions…This stuff has kind of disapeared now, but it was very prevalent in the 70’s- like ‘World’s Biggest Ball of String,’ ‘Bigfoot Museum,’ things like that. So they stumble upon this place called ‘Captain Sapulding’s Museum of Monsters and Madmen.’ It’s basically a serial killer museum in the middle of nowhere, and Captain Sapulding is played by Sid [Spider Baby] Haig- he’s the crazy-looking clown guy. So they go there and learn about this local legend in that area, a murderer called Dr. Satan, whom they find out was killed not too far away. So they want to go take pictures of this site, and once they go off-road in search of this thing, that’s when all hell breaks loose.
