The Roommate

She's cute. She's loyal. She's psychotic. And, unfortunately for college freshman Sara (Minka Kelly) she's THE ROOMMATE. When Sara arrives at school, she finds new romance with Stephen (Cam Gigandet) and forms a fast friendship with her roommate Rebecca (Leighton Meester). What begins as camaraderie soon turns creepy, and Sara comes face-to-face with the terrifying realization that her new best friend is obsessive, unbalanced... and maybe even a killer!
