Megan (Audrina Patridge) enlists the help of her sorority sisters Cassidy (Briana Evigan), Jessica (Leah Pipes), Ellie (Rumer Willis), Claire (Jamie Chung), and Chugs (Margo Harshman) to pull a prank on her boyfriend and Chugs’ brother, Garrett (Matt O'Leary). While having sex with him, Megan fakes her death. Garrett and the girls bring her to a lake, where they intend to dump her body. When Jessica mentions they need to release the air out of her lungs so that her body will not float to the surface, Garrett stabs Megan in the chest with a tire iron, resulting in her actual death. Garrett and the girls cover up the incident and dump Megan's body and the tire iron in a nearby mine shaft. Everyone swears to never mention the incident to anyone, much to Cassidy and Ellie's dismay.
