Twisted Sisters (Dark Pledge)

synopsis

Following the death of her sister, college freshman Sarah joins her mother's former sorority - Psi Kappa Omega - in an attempt to cope. Presided over by Daisy, the chapter's dazzling president, Psi Kaps are the queens of the campus. Sarah becomes Daisy's favorite pledge and is taken under her wing, allowing her to see how the sorority is run more like a ruthless business than a sisterhood. The girls maintain saintly appearances while promoting cutthroat seduction and destruction behind the scenes. Everything from the student body through administration is controlled with bribes and blackmail and Sarah can't help but watch in horror as her world starts to crumble around her.
