Four college friends (including Edward Connell and Barbara Hewitt) head into the woods to visit their professor. However, they find his house has been destroyed and Dr Waterman (Fritz Leiber Jr) is missing. What has been left behind is a mysterious book, when they read the book they find it is an occult tome and Waterman may have opened a portal to Hell. Opps!
A demon is now loose in the woods, posing as the park ranger (Jack Woods), and wants the book. He is willing to unleash a wave of hellish horrors on the four young people to get ahold of the book. The story is told in flashback.
This isn't that great a film, though the demons are a tasty bit of stop motion animation. The budget was minute but the film makers did manage to make the most of it.
