A powerful, hated, and accursed warlock (Julian Sands) from 17th century America is preserved through burial rites and reanimated in the 20th century. He emerges in a foreign society that doesn't respect his power as an agent of the Devil. An equally-powerful witch-hunter Giles Redferne (Richard E. Grant) is also also bound, through magic, to locate the warlock where ever and whenever he may appear. Warlock is a collision between ancient sentiment and modern notions of sin, violence, sex, and superstition.
The warlock awakes in a modern town seeking elements of an ancient text, the Grand Grimoire, that somehow will bestow upon him the revelation of the true name of God, and the consequent power to deconstruct creation. His hunter must avert all attempts at finalizing the mission while befriending and recruiting a few unlucky people, wondering why their town is being turned on-end. A quiet and pastoral rural atmosphere is transformed through the evil intent of a powerful agent of Satan let loose in a time where most people cannot recognize his maligned intent.
Golden fields, livestock, superstition, lore, and ancient rites collide in a centuries-old chase that puts a few modern characters in the deadly wake of the oldest conflict imaginable.
