Here is what the DVD case has to say:
"In the summer of 1979, a group of Detroit friends with $375,000 raised from local investigators headed for a cabin outside of Morristown, Tennessee to make a film about five college studies possessed by an ancient 'Book of the Dead". The filmmakers' goal was to create the 'The Ultimate Experience in Grueling Terror,' a movie so relentless that it would stand forever as a landmark in modern horror history. When it was released in 1982, it was immediately recognized worldwide as one of the most ferociously original films ever made."
This movie is an over-the-top explosion of gore, demons who think they are hilarious, creative deaths, and nail-biting entertainment. A must see. A must own. A must share.
