A sorority prank gone wrong leads to a bloody murder spree in this slasher film featuring Rumer Willis, Audrina Patridge, and Carrie Fisher. It was supposed to be a practical joke, but no one was laughing after a girl in the prime of her life had been accidentally murdered. Desperate to go on with their lives and avoid taking responsibility for their actions, the surviving sisters and their male accomplice agree to dump the body and never speak of the incident again. Just after graduation, however, a mysterious killer begins stalking everyone who harbors the bloody secret, leading the survivors to fight for their lives against a masked maniac with a deadly modus operandi. ~ Jason Buchanan, Rovi
