Promotional materials for this Michigan-based occult turkey (aka Devil Master) proudly proclaimed, "At last! The truth about demons!" So much for truth in advertising... unless the ads refer to the personal demons haunting writer/producer/director/honeywagon driver Donald G. Jackson and his partner in crime Jerry "Nine Fingers" Younkins, who helped finance the film with insurance money after injuring his hand. Younkins also plays the title character -- a dorky, kung-fu hippie satanist who conjures demons to whack various backsliding ex-members of his cult. Gory antics ensue, including a squirm-inducing scene wherein one victim gets an arrow to the crotch... which could be seen as a metaphor for this film's overall effect on the viewer. "Leatherface" Gunnar Hansen also puts in a quick cameo as an occult historian. Amazingly, this no-budget nonsense was the subject of a little-seen documentary titled Demon Lover Diary.
