This eerie film is set circa 1640 , when is earthed by a farmer (Barry Andrews) a weird human remains located in an British small village . Later on , a farming community is haunted by the demon himself . Children and adolescents being possessed by hairy demon and becoming them into a coven of witches practicing exorcisms and witchery . The teens led by a nasty young girl (Linda Hayden) are worshipping the devil , raping , and sacrificing other young people . Meantime , a judge (Patrick Wymark) investigates the rare events .

The film packs gruesome images , grisly killings , thriller and intense horror sequences . Magnificent detail period is perfectly set in 17th century . Somewhat nudism at times in charge of Lynda Hayden and pagans ceremonies . For its US release the nudity was censored, particularly in Linda Hayden’s seduction scene , by darkening the footage to avoid an X rating . Enjoyable casting by Patrick Wymark (a role ¨Witchfinder general¨-alike) who died slowly after making the film , a gorgeous and erotic Linda Hayden (Taste of Dracula blood) , Barry Andrews (Dracula has risen from grave) , Michele Dotrice(who married to Edward Woodward) and Tamara Ustinov (daughter of Peter Ustinov and niece of Angela Lansbury) . It’s produced by Tigon , usual in terror movies and richly atmospheric in Pinewood studios . The movie displays a weird and creepy score musical by Marc Williamson . Evocative and imaginative cinematography by Dick Bush , Hammer films ordinary (Twins of evil , Dracula 72 , When dinosaurs ruled earth). The motion picture was well directed by Piers Haggard (Venom , Quatermass conclusion) . The flick isn’t for the faint-hearted , however to be liked for horror fans.
