Becky, Paige, and Jessie’s European vacation becomes a nightmare as they seek help in the castle of the twisted Dr. Frankie Steinn, unaware of the horrors inside.

In Dr. Steinn’s dungeon, the girls fall into the hands of a lust-driven doctor and her sadistic assistant Igor, becoming unwilling subjects of their perverse experiments.

The monstrous creation—pieced together from corpses and imbued with a criminal mind—awakens, adding even more danger and depravity to the girls' already dire situation.

As the monster comes to life, it too falls under the sway of its evil creators, using its formidable size and strength to further dominate the terrified captives.

Dr. Steinn’s sinister obsession with control and dominance turns the castle into a lair of carnal torment, as she indulges in her deepest desires with the helpless girls.
