Melissa Taub as Erica
Young seniors in an all girl Catholic school rebel against the system when they find a secret wall in a sealed off section of the rectory as well as a book of spells, with which they try to summon He Who Comes, a demon from hell. The horned entity arrives for a less than exciting climax, preceded by some of the girls becoming possessed and turning evil. Zelda Rubinstein also does her weird stuff as a "guardian" nun.
