Description
During his time in Smith's Grove Sanitarium, a young Michael Myers is visited by his mother Deborah who gives him a white horse statuette as a gift.
Fifteen years later, Laurie Strode is wandering around in shock after having shot an adult Michael. Sheriff Lee Brackett finds Laurie and takes her to the hospital. Meanwhile, the paramedics pick up Annie Brackett and Michael's psychiatrist Dr. Sam Loomis, who survived being attacked by Michael, and also take them to the hospital. Michael's body is taken in another ambulance. When the driver has a traffic accident, Michael awakens and escapes, killing a paramedic injured in the accident.
Two years later, Laurie is now living with the Bracketts. Michael has been missing and is presumed dead. While Laurie deals with her trauma, Dr. Loomis has chosen to turn the event into an opportunity to write another book. Elsewhere, Michael, who is still alive and living as a drifter, has been having visions of his mother's ghost and a younger version of himself, who instruct him to reunite with Laurie. Michael arrives at a farm and kills the owners before he sets off for Haddonfield. As Michael travels to Haddonfield, Laurie begins having hallucinations that mirrored Michael's past. Her hallucinations also begin to include her acting out Michael's murders. Meanwhile, Loomis goes on tour to promote his new book, only to be criticized by the public, who blame him for Michael's actions and for exploiting the deaths of Michael's victims. When Loomis' book is released, Laurie discovers that she is really Angel Myers, Michael's long-lost sister. She goes to a Halloween party with her co-workers Mya and Harley to escape how she is feeling.
Michael appears at the party and kills Harley, then goes to the Brackett house and fatally wounds Annie. When Laurie and Mya return to the house, they find Annie, who dies in Laurie's arms. Michael kills Mya and then comes after Laurie, who manages to escape. Sheriff Brackett arrives home and finds his daughter dead. Laurie flags down a car, but Michael kills the driver and flips the car over with Laurie still inside. Michael then takes the unconscious Laurie to an abandoned shed. Laurie awakens to her hallucinations with Deborah, seen by both her and Michael, who asks for her to call her "mommy".
The police discover Michael's location and surround the shed. Loomis arrives and goes inside to try to reason with Michael but when he tries to resusciate Laurie from her hallucinations, Michael grabs Loomis and stabs him to death, before being shot through the cabin window by Brackett and impaled on a rake. Apparently released from her visions, Laurie walks over to Michael and stabs him to death with his own knife. The shed door opens and Laurie walks out, wearing Michael's mask. Later, Laurie sits in isolation in a psychiatric ward, grinning as Deborah's ghost approaches with the horse.
