Someone has been performing the Black Mass in an old, abandoned chapel at Stanton Rocks. The local priest, Tom Pridough, is convinced it was Nich Mordaunt, local high-profile pagan, and his friend, the stunning brunette Juliana. Tired of the churchman's confusion of diabolism with his own nature-worship. Nich too sets out to find out who is responsible, and all three become embroiled in a weired and perverse world of sex-magic.
