Sidney Prescott is a Woodsboro teenager. In "Scream", a year after the murder of her mother Maureen, she is stalked by a killer, later revealed to be her boyfriend Billy Loomis and his friend Stu Macher. These two prove to have been Maureen's murderers, Billy being motivated by Maureen's affair with his father, which caused his mother to leave home. Sidney kills both of them in self-defense. In "Scream 2", while attending college, she again becomes the target of a masked killer, this time her boyfriend's friend Mickey and the mother of Billy Loomis, seeking revenge for the death of her son. Once more Sidney manages to survive the attempts on her life. During "Scream 3" she is drawn to Hollywood by yet another killer. She discovers that this one is her half-brother Roman Bridger, who wants to kill her out of anger at his abandonment by Maureen. In "Scream 4" she returns to Woodsboro to promote her new self-help book about overcoming the tragedies of her life, but is targeted once again by a new Ghostface, who turns out to be her cousin Jill Roberts who's envious of Sidney's fame and wants to become the new "Sidney Prescott".
