Christine has a big opportunity to showcase her modelling skills when she applies to Sybil Waite's agency. Together with her sister Betty, they head to a castle for the weekend for a photo shoot. Sybil has invited Christine to the castle not just for the photo shoot but also to recruit a virgin for induction into a witch's coven, led by the owner of the castle, Gerald. To their surprise, Christine is eager to join the coven, but begins her own secret battle for control.
