Taken from Bram Stoker's last novel, Ken Russell adds his artistic flair to this campy horror comedy. While staying at the ancestral home of sisters Mary (Sammi Davis) and Eve Trent (Catherine Oxenberg), a Scottish archaeology student uncovers a skull of unknown origin. Angus Flint (Peter Capaldi) reveals his findings to the neighboring nobleman Lord James (Hugh Grant). The two connect the ancient legends of a dragon to a strange cult that worships a giant, ravenous subterranean white worm. The property of the Trent sisters is later revealed to have been built on the sight where ancient pagan rituals took place. Vampire vixen and cult-member Lady Silvia Marsh (Amanda Donohoe) lures victims to the white worm to feed on.
