The Initiation of Sarah (1978)

When the popular Patty Goodwin and her beloved, but outcast stepsister Sarah Goodwin join the university, they drive to the dormitory of the campus first to pledge sororities later. They apply to the famous Alpha Nu Sigm, where their mother stayed in her academic life, but only Patty is accepted. Sarah needs to go to the unpopular Phi Epsilon Delta house that accepted her, and the two sisters are split. Sarah immediately befriends the shy musician Alberta "Mouse" and has an interview with the notorious "mother" Mrs. Erica Hunter. Then, she gets close to the young assistant professor Paul Yates that tells that Mrs. Hunter has an obscure past and used to dedicate to the occultism. Further, the rivalry between the two sorority houses is not recent and he advises her to leave the Phi Epsilon Delta. Meanwhile, the cruel leader of Alpha Nu Sigm Jennifer Lawrence tries to separate Patty and Sarah, provoking a reaction from Sarah. Soon Mrs. Hunter learns that Sarah has powerful telekinetic and psychic abilities when she is angry, and decides to use her power to destroy Alpha Nu Sigm sorority.
