Halloween - 2007
On Halloween in Haddonfield, Illinois, having already shown signs of psychopathic tendencies, ten-year-old Michael Myers (Daeg Faerch) murders a school bully. Later that evening, he murders his older sister Judith (Hanna R. Hall), his mother´┐Żs abusive boyfriend Ronnie (William Forsythe), and Judith's boyfriend Steve (Adam Weisman). Only his baby sister, Angel Myers, is spared. After one of the longest trials in the state´┐Żs history, Michael is found guilty of first degree murder
He is sent to Smith's Grove - Warren County Sanitarium under the care of child psychologist Dr. Samuel Loomis (Malcolm McDowell). Michael initially cooperates with Dr. Loomis, claiming no memory of the killings; his mother, Deborah (Sheri Moon Zombie), visits him regularly. While incarcerated at Smith's Grove, Michael becomes fixated on his papier-m´┐Żch´┐Ż masks, closing himself off from everyone, even his mother.
When Michael kills a nurse as Deborah is leaving from one of her visits, she can no longer handle the situation and commits suicide. For the next fifteen years, Michael (Tyler Mane) continues making his masks and not speaking to anyone. Dr. Loomis, having continued to treat Michael over the years, attempts to move on with his life and closes Michael´┐Żs case.
Later, while being prepared for transfer to maximum security, Michael escapes Smith´┐Żs Grove, killing the sanitarium employees and a truck driver for his overalls, and makes his way back to Haddonfield. On Halloween, Michael arrives at his old home, now abandoned, and recovers the kitchen knife and Halloween mask he stored under the floorboards the night he killed his sister.
The story shifts to Laurie Strode (Scout Taylor-Compton), and her friends Annie Brackett (Danielle Harris) and Lynda Van Der Klok (Kristina Klebe) on Halloween. Throughout the day, Laurie witnesses Michael watching her from a distance. That night, she heads to the Doyle residence to watch their son Tommy (Skyler Gisondo). Meanwhile, Lynda meets with her boyfriend Bob (Nick Mennell) at Michael's childhood home.
Michael murders them, and then heads to the Strode home, where he murders Laurie's parents, Mason (Pat Skipper) and Cynthia (Dee Wallace). Dr. Loomis, having been alerted of Michael's escape, comes to Haddonfield looking for him. After obtaining a handgun, Loomis attempts to warn Sheriff Brackett (Brad Dourif) that Michael has returned to Haddonfield. Brackett and Dr. Loomis head to the Strode home, with Brackett explaining along the way that Laurie is actually Michael's baby sister.
Meanwhile, Annie convinces Laurie to babysit Lindsey Wallace (Jenny Gregg Stewart), a girl Annie is supposed to be watching, so she can have sex with her boyfriend Paul (Max Van Ville). Annie and Paul return to the Wallace home and during sex, Michael kills Paul and attacks Annie. Bringing Lindsey home, Laurie finds Annie on the floor, bloodied but alive, and calls the police.
She is attacked by Michael, who chases her back to the Doyle home. Sheriff Brackett and Loomis hear the call announced over the radio and head toward the Wallace residence. Meanwhile, Michael kidnaps Laurie and takes her back to his home. Michael approaches Laurie and tries to show her that she is his younger sister, presenting a photo of the siblings with their mother.
Unable to understand, Laurie grabs Michael's knife and stabs him before escaping the house; Michael chases her, but is repeatedly shot by Dr. Loomis. Laurie and Loomis are just about to leave when Michael grabs Laurie and heads back to the house. Loomis intervenes and tries to reason with Michael, but Michael attacks him by squeezing Loomis's skull with his hands.
Laurie takes Loomis's gun and runs upstairs; she is chased by Michael, who, after cornering her on a balcony, charges her head-on, knocking both of them over the railing. Laurie finds herself on top of a bleeding Michael. Aiming Loomis' gun at his face, she repeatedly pulls the trigger until the gun finally goes off just as Michael's hand grips Laurie's wrist.
Halloween II - 2009
In a flashback, Deborah Myers (Sheri Moon Zombie) visits her son, a young Michael Myers (Chase Wright Vanek), at Smith's Grove Sanitarium. She gives him a white horse statuette as a gift. Michael says that the horse reminds him of a dream he had of Deborah's ghost, dressed in all white and leading a horse down the sanitarium halls toward Michael, telling him she was going to bring him home.
Fifteen years later, after having shot an adult Michael (Tyler Mane), Laurie Strode (Scout Taylor-Compton) is found wandering around in a state of shock by Sheriff Brackett (Brad Dourif), who takes Laurie to the emergency room. Meanwhile, the paramedics pick up the Sheriff's daughter and Laurie's friend Annie (Danielle Harris) and Michael's psychiatrist Dr. Loomis (Malcolm McDowell), who are still alive after having been attacked by Michael, and take them to the hospital.
Presumed dead, Michael's body is loaded into a separate ambulance. When the driver has a traffic accident, Michael awakens and escapes the ambulance, walking toward a vision of his mother dressed in white and leading a white horse. Michael appears at the hospital, and begins murdering everyone he comes across on his way to Laurie. Trapped in a security outpost at the gate, Laurie watches as Michael tears through the walls with an ax, but just as he tries to kill her, Laurie wakes up from the dream.
It is actually one year later and Laurie is now living with the Bracketts. Michael has been missing since last Halloween´┐Żstill presumed dead´┐Żand Laurie has been having recurring nightmares about the event. While Laurie deals with her trauma through therapy, Dr. Loomis has chosen to turn the event into an opportunity to write another book. Meanwhile, Michael has been having visions of Deborah's ghost and a younger version of himself, who instructs him that with Halloween approaching it is time to bring Laurie home; so he sets off for Haddonfield.
As Michael travels to Haddonfield, Laurie begins having hallucinations that mirror Michael's, which involve a ghostly image of Deborah and a young Michael in a clown costume. In addition, her hallucinations also begin to include her acting out Michael's murders, like envisioning herself taping Annie to a chair and slitting her throat while dressed in a clown outfit´┐Żsimilar to how a young Michael murdered Ronnie White.
While Laurie struggles with her dreams, Loomis has been going on tour to promote his new book, only to be greeted with criticism from people who blame him for Michael's actions and for exploiting the deaths of Michael's victims. When his book is released, Laurie discovers that she is really Angel Myers, Michael's long lost sister. With the truth out, she decides to go to a party with Mya (Brea Grant) and Harley (Angela Trimbur) to escape how she is feeling.
Michael appears at the party and kills Harley, then makes his way over to the Brackett house and stabs Annie repeatedly. When Laurie and Mya arrive they find Annie bloodied and dying. Michael kills Mya and then comes after Laurie, who manages to escape the house. While Laurie manages to flag down a passing motorist, Sheriff Brackett arrives home and finds his daughter dead.
Laurie gets into the motorist's car, but before they can escape Michael kills the driver and flips the car over with Laurie still in it. Michael takes the unconscious Laurie to an abandoned shed he has been camping out in. Laurie awakens to a vision of Deborah, and a young Michael, ordering her to say "I love you, mommy". The police discover Michael's location and surround the shed. Loomis arrives and goes into the shed to try to reason Michael into letting Laurie go.
Inside, he has to inform Laurie, who believes that the younger Michael is holding her down, that no one is restraining her and that she must maintain her sanity. Just then, Deborah instructs the older Michael that it is time to go home, and Michael grabs Loomis and kills him by slashing his face and stabbing him in the chest. Stepping in front of a window while holding Loomis's body, Michael is shot twice by Sheriff Brackett and falls into the spikes of some farming equipment.
Apparently released of the visions, Laurie walks over and tells Michael she loves him, then stabs him repeatedly in the chest and finally in the face. The shed door opens and Laurie walks out, wearing Michael's mask. As she pulls the mask off, the scene transitions to Laurie in isolation in a psychiatric ward, grinning as a vision of Deborah dressed in white stands with a white horse at the end of her room.
