Halloween Party

On Halloween night in 2019, 21-year-old Corey Cunningham babysits a young boy named Jeremy Allen who pulls a prank on him by locking him inside the attic. Just as Jeremy's parents come home, Corey kicks the door open and accidentally knocks Jeremy over a staircase railing to his death. Corey is arrested for aggravated manslaughter, but is cleared by the judge. Nonetheless, Corey is made an outcast by the citizens of Haddonfield, Illinois. Three years later, Haddonfield is still reeling from the aftermath of Michael Myers's latest killing spree in 2018, while Michael has vanished. Laurie Strode is writing a memoir and living with her granddaughter Allyson. Meanwhile, Corey is working at his stepfather's salvage yard. On his way home one day, he is accosted by high school bullies and injures himself in the process. Laurie, having witnessed the incident, brings Corey to the doctor's office where Allyson is working herself. Allyson and Corey agree to a date at a Halloween party, where Corey is confronted by Mrs. Allen when she recognizes him. Corey leaves the party and runs into the bullies who throw him off a bridge. Unconscious, he is dragged into the sewers where Michael resides and is choked by him, but Michael eventually lets him go. As he crawls out, Corey is threatened by a homeless man. In a struggle, Corey stabs the man to death and flees. During a dinner date, Corey and Allyson are harassed by her ex-boyfriend, an officer who previously arrested Corey for Jeremy's death. Corey later retaliates by luring him into the sewer to be killed by Michael. Soon after, Allyson is passed over for a promotion at work, in favor of a nurse who is having an affair with the doctor. When Corey finds out about this, he kills the doctor at his home while Michael kills the nurse. Allyson, unaware of Corey's murders, plans to leave Haddonfield with an insistent Corey to escape their trauma. Speaking with Jeremy's father, Laurie realizes Corey is "infected" by Michael's evil, but her wariness fractures her and Allyson's relationship. On Halloween day, Corey, after sleeping in the spot where Jeremy died, finds himself confronted by Laurie, who offers help on the condition he ends things with Allyson, only for Corey to rebuke her and state that if he cannot have Allyson, no one will. Corey returns to the sewers where he overpowers Michael for his mask. Corey embarks on a rampage, murdering the bullies after luring them to the salvage yard, one of whom accidentally kills Corey's stepfather. Corey goes on to kill his mother, and a DJ at a local radio station who had taunted him earlier. Eventually, Corey is lured to the Strode house when Laurie fakes a suicide attempt to ambush him. When Laurie shoots him down the stairs, Corey stabs himself in the neck to frame Laurie for his death in front of the arriving Allyson, who leaves in distress. Moments later, Michael arrives to retrieve his mask, killing Corey by breaking his neck. Michael then searches for Laurie in her house, and the two engage in a violent fight, ending with Laurie pinning Michael to the table. Laurie unmasks Michael, declaring he's not the boogeyman, but merely a man, before slitting his throat. Michael yanks his injured hand free and begins to choke Laurie. However, Allyson — having learned the truth about Corey's murders and death after receiving a call from Deputy Frank Hawkins — returns in time to break Michael's arm. After Laurie slices Michael's wrists, Michael bleeds out and finally dies. Laurie and Allyson take Michael's body to the salvage yard by police escort attracting the residents of Haddonfield, who follow them in a procession. They watch as Laurie disposes of Michael's body in an industrial shredder, signaling the end of Michael's reign of terror. In the aftermath, Allyson and Laurie reconcile from the ensuing days and Allyson eventually leaves Haddonfield while Laurie finishes her memoir and rediscovers her romance with Hawkins. The last shot of the film shows that Laurie kept Michael's mask.
