The Curse of Bigfoot

This film is comprised of a hoary monster movie from the early '60s with new footage tacked on to the beginning and end. The framing story is set in a high school classroom where an old teacher, discussing the limitations of knowledge, tells them a strange tale from his youth about how he and some friends once found odd remains in an Indian burial ground, and how, once they went to investigate further, found the sacred site was guarded by a scary monster.
