The first of three legendary collaborations between onetime exploitation filmmakers Ron and June Ormond and Baptist minister Estus W. Pirkle, this film was rarely screened outside of churches and religious organizations – never to the general public. As a breathless warning of the dangers of the “Communist menace” in rural Christian America, it is an astonishing, no-holds-barred evangelical thriller-cum-sermon that has no cinematic peer… except for its equally astonishing follow-up, The Burning Hell, made three years later.
