Plot Sara Matthews is starting her freshman year of college in Los Angeles. She meets party girl Tracy, frat boy Stephen—her love interest—and Rebecca, her shy college roommate who bears an uncanny resemblance to her. The girls begin to bond and Rebecca learns that Sara had an older sister, Emily, who died when Sara was nine, and an ex-boyfriend, Jason, who keeps calling her in attempts to reconcile. Over time, Rebecca's obsession with Sara grows, which causes her to drive away anyone who could come between them. Claiming that she is a bad influence, Rebecca attacks Tracy in the shower, pins her down, rips out her belly-button ring, and threatens to kill her unless she stays away from Sara. Tracy moves to another dorm, fearful of Rebecca. An old friend of Sara's named Irene invites Sara to move in with her when Sara's cat Cuddles is discovered by an RA. Rebecca kills Cuddles, lying to Sara that the cat ran away, and inflicts injuries upon herself and says she was assaulted by a thug. Feeling sympathetic, Sara decides to spend Thanksgiving with Rebecca. When Sara's fashion design professor, Roberts, kisses her, Rebecca plans to get the professor out of the picture by seducing him while recording their dialogue on a tape recorder to make it sound like he was trying to rape her. During her Thanksgiving stay, Sara overhears a conversation between Rebecca and her father, hinting Rebecca has had trouble making friends in the past. After Rebecca's mother mentions that Rebecca is supposed to be taking medication, Sara and Stephen find a bottle of unused Zyprexa pills, used to treat schizophrenia or bipolar disorder. Sara decides to move in with Irene; however, that evening at a club, Rebecca seduces Irene and they go back to Irene's place. The following morning, Sara goes to Irene's apartment, but she is not there. Meanwhile, Rebecca gets Sara's sister's name tattooed in the same place on her breast as Sara. Alarmed, Sara finally realizes Rebecca is obsessed with her and removes her belongings from the dorm. Jason arrives at Sara's dorm and slips a note under
