Elvira (Cassandra Peterson) is headed for Paris in the company of her maid, Zou Zou (Mary Jo Smith), when they come across Lord Vladimere Hellsubus (Richard O'Brien). Presumably failing to note the warning signs inherent in the Lord's surname, the pair are enticed into his castle, where Vladimere's obsession for Elvira, fuelled by her similarity to his deceased wife, sees him pursue her through the castle.

Will the enterprising Elvira and her maid manage to stay out of the clutches of Hellsubus and make their escape?
