Sorority Row - Coming soon.....

http://sororityrowmovie.com/

Movie Plot:
Six sorority sisters, Cassidy (Briana Evigan), Jessica (Leah Pipes), Ellie (Rumer Willis), Claire (Jamie Chung), Chugs (Margo Harshman) and Megan (Audrina Patridge) are sworn to trust, secrecy and solidarity, no matter what. But when a prank goes wrong, Megan was brutally murdered and the sisters agreed to hide the body and keep their mouth shut. One year later, they received a video taken on the night of Megan's murder from an anonymous person. Since then, an unseen killer stalks all the girls. Now, the girls are trying to figure out which one of them let the secret slip.

Personally point of view:
I do feel it is similar to "I know what you did last summer." But I still want to catch this movie in theatre. It will be out in cinema on 8th Oct 2009.
