When two young lovers are savagely beaten and tortured on a back country road in Texarkana, local police are baffled and must find "the Phantom Killer" before he can kill again.
Disheartened by futile combat, appalled by the corruption of their South Vietnamese ally, and constantly endangered by the incompetence of their own company commander, the young men find a possible way out of the war. They are told that if they purposely lose a soccer game against a South Vietnamese team, they can spend the rest of their tour playing exhibition games behind the lines.
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 The film was originally made in 1967 by Dennis Muren as The Equinox: Journey into the Supernatural.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.
