Sorority Row

Five Theta Pi sorority sisters, Cassidy (Briana Evigan), Jessica, Ellie (Rumer Willis), Chugs Bradley (Margo Harshman) and Megan Blaire (Audrina Patridge), attend a party to celebrate their senior year when they inadvertently cause the death of fellow sister Megan through a prank gone wrong. Eight months later, the girls receive mysterious text messages from an anonymous person threatening to expose their secret, leading them to become stalked and murdered by a masked killer who knows about their role in Megan's accidental death.
