Reunited under the direst of circumstances, the undead brothers Ein and Leroux DeLaLune rush to get the rest of the immortals out of Paris and away from the pagan magic of the witch Elizabeth Bathory. However, the witch is having doubts about her poisonous role in the peaceful existence the brothers have built for the undead over the past 400 years, which could cause a rift between her and Victor Frankenstein, who is carrying out her plan with fervor. The key to saving the undead citizens may rest in the human Dahlia Whyte, who is still reeling from learning that her lover Ein is actually a dark creature of the night.
