Description
On October 31, 1989, Michael Myers and his niece Jamie Lloyd are abducted from the Haddonfield Police Station by the Man in Black and two of his henchmen. Six years later, on October 30, 1995, Jamie gives birth to a baby, and the Man in Black, revealed to be the leader of a Druid-like cult, takes the child away. Later, a midwife helps Jamie escape with her baby, but she is killed by Michael. Jamie and her baby flee in a stolen pick-up truck, with Michael in pursuit. Meanwhile, Dr. Sam Loomis has retired and moved to a cabin on the outskirts of Haddonfield, where he lives as a hermit. He is visited by his friend Dr. Terence Wynn, the chief administrator of Smith's Grove Sanitarium, where Michael had been incarcerated as a boy; Wynn asks Loomis to return to Smith's Grove. They overhear Jamie's plea for help on a local radio station, when she makes a call to Loomis, only to be ignored by the radio D.J. Barry Simms. Michael catches up with Jamie, and she crashes the truck into an old barn. He kills Jamie, but finds that her baby is not in the truck.
In Haddonfield, Tommy Doyle, whom Laurie Strode babysat in 1978, now lives in a boarding house run by Mrs. Blankenship. Tommy is a reclusive individual who has become obsessed with finding the truth behind Michael's motives. The dysfunctional family living in the Myers house across the street are relatives of the Strode family: Kara Strode, her six-year-old son Danny, her teenage brother Tim, caring mother Debra, and abusive father John. Tommy finds Jamie's baby at the bus station, takes him into his care, and names him Steven. Tommy runs into Loomis and tells him about the Strode family living in the Myers house. Meanwhile, Michael returns to Haddonfield, where he stalks Kara, before killing Debra.
Later, Tommy, Kara, and Danny go to the boarding house, where Tommy reveals that he believes Michael has been inflicted with Thorn, an ancient Druid curse. Long ago, one child from each tribe, chosen to bear the curse of Thorn, must sacrifice its next of kin on the night of Samhain, or Halloween. Tommy believes that Steven will be Michael's final sacrifice. Later that night, while Tommy goes out to look for Loomis, Mrs. Blankenship reveals to Kara that she was babysitting Michael the night he killed his sister, and that Danny is hearing a voice telling him to kill just like Michael did, indicating Danny also possesses the power of Thorn. Meanwhile, Michael kills John, Tim, Tim's girlfriend Beth, and Barry Simms. Danny and Kara manage to escape back to the boarding house where Tommy and Loomis are waiting.
The cult arrives at the boarding house, where it is revealed that Mrs. Blankenship is a cult member and the Man in Black is Dr. Wynn. The cult drugs Loomis and Tommy and takes Kara, Danny, and Steven to Smith's Grove. Kara is locked in a maximum security ward while the boys are kept in an operating room. Loomis confronts Wynn, who reveals that the staff at Smith's Grove have been working with the Thorn cult to study the power of Thorn and learn how to control it. Steven is implied to be the successful result of experiments to clone Michael's pure evil, and the cult plans to use Danny and Kara to create another one. Wynn wants Loomis to join in on his conspiracy, as he was the first one to see the evil inside Michael. Loomis refuses and is knocked out by a cult member.
Tommy frees Kara as Michael pursues them through the sanitarium. They find Wynn and his team, who are about to perform a medical procedure on Danny and Steven. Michael suddenly appears and turns against Wynn and the doctors, killing them all. Tommy and Kara rescue the kids and Michael chases them into a laboratory, where Kara notices fetuses from Wynn's failed experiments. Tommy injects Michael with corrosives and beats him unconscious with a lead pipe. Tommy, Kara, and the children leave Smith's Grove while Loomis stays behind to take care of business. Inside, Michael's mask lies alone on the lab floor, and Loomis screams in the background, leaving their fates unknown.
