Sorority Row

"Sorority Row" sees a group of sorority sisters try to cover up the death of their house-sister after a prank gone wrong, only to be stalked by a serial killer.

During a party in the Theta-Pi sorority house, the sister Megan plays a prank with her unstable boyfriend Garrett simulating an OD after using pills. Her sisters Jessica, Claire, Ellie, Cassidy and Garrett's sister Chugs suggest to dump her "body" in a lake and the stressed Garrett sticks the tire iron through the Megan's chest killing her. Cassidy decides to call the police, but the sisters are convinced to dispose the body in a shaft and keep in secret under the leadership of Jessica that blackmails Cassidy. Eight months later, in their graduation party, the sisters receive a creepy message with the picture of the tire iron in the beginning of a nightmarish night.

After finding out a guy cheated on their sister, sorority house Theta Pi play a simple prank on him. They trick him into thinking that he has killed his girlfriend, then take him into the middle of nowhere to 'dismember" the body, only then revealing it was a prank. However, the prank goes horribly wrong and all involved swear never to speak of it again. A year later at graduation though, they are all reminded of the past..
