Creepy but comedic horror yarn about a old Western backwater called Purgatory and it's vampiric citizenry, whose leader (David Carradine) has gotten them to kick the habit of human blood, and sustain themselves on a synthetic substitute. But a rebel bloodsucker (Maxwell Caulfield) and his acolytes want the real thing-and they just might get it when an unsuspecting family moves into town. Deborah Foreman, Morgan Brittany, John Ireland, and Bruce Campbell also star. 104 min. Widescreen: Soundtrack: English.
