五个女巫,五种力量,一个恶魔 Mark街的天主教女子学校自从一名年轻的学生无影无踪地突然消失以后就被关闭和废弃了。但是在13年以后,在一名专横跋扈的女校长和一名有着麻烦过去牧师的领导下,这所学校重新开启。现在,五名叛逆的学生因被学校要求自我赎回而被关押起来。当这些女孩子团结起来试图利用各自的超能力逃跑时,她们意识到,为了生存,她们必须同远古邪灵及它所奴役的学校做殊死搏斗。In St. Marks catholic boarding school for girls, the religious student Elizabeth is attacked by evil forces and disappears from the classroom and the impotent Father Drake is incapable of saving her. The school is closed and five years later it is reopened. Five troubled unwanted girls - Alex, Mara, the blind Cecilia, Leah and Connie - are left by their family in the institution, severely directed by the headmistress Miss Pearce with hands of iron. Father Drake is their teacher and the girls are forbidden to go to the mysterious third floor. When Alex has visions of the possessed Elizabeth, weird things happen in the spot and the girls have to fight against a legion of two thousand demons.
