Synopsis: Halloween is the perfect excuse to watch all the over-the-top, terrible fright-fests you avoided at the theater. Er, not that this is one of those. Rebecca (Meester) is just your average college co-ed with an obsession/murder problem. When Sara meets her new roomie, the two girls bond quickly. Then things go to Hell in a handbag when Rebecca starts killing off her rivals for Sara’s attention. Think Single White Female, The College Years.
