The Milton Estate is a central location in Scream 3.
Producer John Milton invites the cast to a party at his house. Director Roman Bridger and Jennifer check out the basement while Tyson Fox and Angelina explore the house. After realizing that the killer has tricked them into congregating at the house, Dewey and Gale split up to round up the cast and escape. Gale stumbles upon Roman's body in a chest, but she meets Jennifer and Angelina. Extremely scared, Angelina runs off alone and is murdered. The killer brazenly attacks the remaining four and wounds Dewey and Tyson. He chases Tyson and throws him over the balcony, killing him. Meanwhile, in the shuffle, Jennifer falls into a hidden passage which happens to be connected to the room where Dewey and Gale are hiding by a one-sided mirror. She meets the killer and becomes the next victim in an ironic twist where Jennifer is banging on the mirror from her side to escape her attacker. Dewey then shoots the mirror, but is too slow and she is stabbed to death. The killer next attacks Gale and knocks out Dewey. He holds them hostage to draw Sidney to the house. Sidney preempts his moves and shoots him, but before she can release Gale and Dewey, he escapes. Kincaid arrives on the scene and saves Sidney from an attack by the killer, but Kincaid is rendered unconscious.
The killer chases Sidney to a room, and he reveals himself to be Roman (who had faked his own murder), the connection being that he is Maureen's illegitimate son and Sidney's half-brother. He brings out John (who had been gagged and stuffed at a corner of the room) and kills him in front of Sidney. It is further revealed that Roman is a product of rape, which occurred during Maureen's brief stint as a B-list movie actress. Roman tells Sidney that her mother cheated on her father with Cotton Weary and Hank Loomis, causing Mrs. Loomis to leave her husband. Roman managed to track down Maureen and revealed himself to be her son but she slammed the door in his face. Swearing revenge, Roman told Billy Loomis why his mother had left his father, and convinced him to kill Maureen. Roman also told Billy to have an accomplice who was weak and easily willing to help him out, which turned out to be Stu Macher which ultimately triggered the events of the first movie and that of the second. It is revealed that John Milton was Roman's father.
Tired of hearing another killer blaming the circumstances of their life on her. Sidney berates Roman who gets angered enough to attack her leading to a fight. Roman manages to gain the upper hand but a distraction by Kincaid allows Sidney to grab his knife. He however finds Kincaid's gun and shoots her, knocking her down. He shoots her in the chest to be certain in killing her. But Dewey and Gale on the verge of breaking into room distracts him for a moment, when he turns around, Sidney is gone. Roman tears the room apart trying to find her before going to use his cell phone to locate her. Sidney beats him to punch using a phone to catch him off guard before poping up from behind the bar, stabbing him several times in the back before stabbing him in the heart. As Roman dies, Sidney reveals she had a bulletpoof vest on as well, commenting they weren't so different. The two siblings seem to reconcile. But just as Dewey and Gale arrive, Roman jumps up to attack them again. But Dewey stuns him with several shots to the chest before, on the advice of Sidney, finishes Roman with a headshot, killing him for good.
