Equinox
Due to their possession of an ancient mystic book, four friends are attacked by a demon while on a picnic and find themselves pitched into a world of evil that overlaps their own. The film was originally made in 1967 by Dennis Muren as The Equinox: Journey into the Supernatural. Jack Woods was hired to shoot additional footage and expand on Muren's work.
