Warlock

“Satan also has one son.”

Giles Redferne (Richard E. Grant) is a witch hunter in 17th century New England who finally has a warlock in chains, until the condemned man gets help from Satan and vanishes. He lands in the 1980s with a plan to end the world, and Giles follows him into a century he doesn't understand, a young woman, Kassandra (Lori Singer), his only guide. Steve Miner keeps it moving at the pace of a late-night creature feature.
