In Scream 1996 the two killers behind the Ghostface mask are Billy Loomis and Stu Macher, and the full plot builds toward that reveal. A masked caller quizzes Casey Becker about horror movies, then kills her and her boyfriend. Sidney Prescott is attacked at home by the same killer, who wears a black robe and a ghost mask. She fights him off, and suspicion falls on her boyfriend Billy Loomis, who is held by the police and then released.
Meanwhile, reporter Gale Weathers pushes the theory that Cotton Weary, the man convicted of Sidney's mother's murder, is innocent. The school closes and the killer keeps striking, claiming more victims among the locals. Randy, the film obsessed friend, explains the unwritten rules that horror victims follow, and the group takes that talk to a party at Stu's house, where the teens drink, watch scary movies and the body count rises.
Sidney finally gives in to Billy, and then he and Stu step out as the two killers. Billy reveals that he blamed Sidney's mother for breaking up his family. The pair stab each other to make their story look believable, and they plan to frame Sidney's father.
The plan does not hold. Sidney, helped by a wounded Gale and by Dewey, turns the tables, and Randy is nearly killed along the way. Sidney kills Stu, and then she shoots Billy in the head when he rises one last time. As such, the film ends with both killers dead and the survivors being tended to outside the house.
