The Sisterhood (2005)

In order to be accepted by BATS, the most elite (and deadly) sorority on campus, Christine will have to demonstrate more than just school spirit. While Christine begins the pledge process with the good intentions of putting an end to this wicked institution, her strength of character is put to the ultimate test as her new sisters try to win her over with their menacing powers. Will the guidance of her abnormal psychology professor (Barbara Crampton of RE-ANIMATOR) be enough to save Christine, or will the witchcraft, torture, and mind control tactics used by the sorority sorceresses deliver her to the same fate as the countless naive freshmen before her?
