The Devil Rides Out - 1968

As the Duc de Richelieu wrestles with the Satanist for the soul of his friend the forces of good have been pitted against the forces of evil. Mocata has got the wisdom and the capability to summon the powers of darkness and, until thundering hooves herald the birth of this Angel of Death, like the Duc de Richelieu and his friends remain inside the pentacle, they're exposed.
