The Dæmons
The Master, posing as a rural vicar, summons a cloven-hoofed demon-like creature named Azal in a church crypt. Seeking to gain the ancient titan's demonic power, he gathers a cult and then corrupts or controls the residents of Devil's End to bow to his will.
Dark elemental forces begin to disturb the village on the eve of May Day: unexplained murders, a stone gargoyle come to life, and a nigh-impenetrable infernal energy dome. With the Master fully prepared to destroy the Earth, the Doctor and UNIT — aided by a benevolent practitioner of witchcraft — battle the wicked rites of a secret science wielded by an alien from another world.
