Former military man Captain Kronos (Horst Janson) is bent on revenge; vampires abducted his wife and child, and now it's payback time. Having recruited the vampire expert Professor Grost (John Cater), Kronos is ready to hunt down the bloodsuckers at all costs. Their destination? A small village in England where the evil creatures of the night are sucking the youth -- not just the blood -- out of their prey.
