Virgin Witch (1971)

Christine gets her big chance at modeling when she applies at Sybil Waite's agency. Together with Christine's sister Betty they go to a house in the country for the weekend for a photo shoot. Sybil has lured Christine to the castle for more than modeling: she is recruiting a virgin for induction into a witch's coven, led by the owner of the castle, Gerald. To their surprise, Christine is more than eager to join the coven, but begins her own secret battle for control.
