Boston, 1691. The gallows await the Warlock (Julian Sands). What was an apparent triumph of Witch Hunter Giles Redferne (Richard E. Grant), is short lived as the Warlock escapes and is hurled 300 years into the future. Now, say a prayer for the City of Angels, for it is here in Los Angeles where he begins the task of reuniting three portions of the Devil's Book that will reveal the secret name of God. If spoken, all creation will be destroyed. Redferne, who is also transported, enlists the aid of Kassandra (Lori Singer), who has miraculously escaped the Warlock's wrath. But the carnage has begun as the Warlock successfully unites the first two sections. The final portion is buried in an old Boston cemetery; in Redferne's grave! It is on these hallowed grounds where evil magic will confront the strength of righteouness with the future of mankind at stake.
