She'll Blow Your Mind!
Virgin Witch is a 1971 British horror exploitation film about a prospective model who ends up joining a coven of witches.
Christine gets her big chance at modelling when she applies at Sybil Waite's agency. Together with Christine's sister Betty they go to a castle for the weekend for a photo shoot. Sybil has lured Christine to the castle for more than modelling: 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. Written by Ed Sutton <firstname.lastname@example.org>
