On Halloween in Haddonfield, Illinois, having already shown signs of psychopathic tendencies, ten year old Michael Myers (Daeg Faerch) murders his sister Judith (Hanna R. Hall), her boyfriend Steve (Adam Weisman), his motherâ€™s boyfriend Ronnie (William Forsythe), and a school bully (Daryl Sabara). After the longest trial in the stateâ€™s history, Michael is found guilty of first degree murder and sent to Smith’s Grove – Warren County Sanitarium under the care of child psychologist Dr. Sam Loomis (Malcolm McDowell).
Michael initially cooperates with Dr. Loomis, claiming no memory of the killings; his mother, Deborah (Sheri Moon Zombie), visits him regularly. After a year, Michael becomes fixated on his papier-mÃ¢chÃ© masks, closing himself off from everyone, even his mother. When Michael kills a nurse (Sybil Danning) during one of her visits, Deborah 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 Michaelâ€™s case. Later, while being prepared for transfer to maximum security, Michael escapes Smithâ€™s Grove, killing the sanitarium guards and a truck driver (Ken Foree) for his clothes, and heads to Haddonfield. On Halloween, Michael arrives at his old home, now abandoned, and finds a kitchen knife and Halloween mask he stored under the floorboards the night he killed his sister.
Meanwhile, Annie convinces Laurie to babysit Lindsey Wallace (Jenny Gregg Stewart), a girl Annie is supposed to be watching, long enough so she can have sex with her boyfriend Paul (Max Van Ville). Annie and Paul return to the Wallace home; during sex, Michael kills Paul and attacks Annie. Bringing Lindsey home, Laurie finds Annie on the floor, bloodied but alive, and calls 911. She is attacked by Michael, who chases her back to the Doyle home. Sheriff Brackett and Loomis hear the 911 call and head to the Wallace residence. Michael kidnaps Laurie, and takes her back to his home. Michael approaches Laurie and tries to show her that she is his younger sister. 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, but Michael attacks him by squeezing Loomis’s skull with his hands. Laurie takes Loomis’ gun and runs upstairs; she is chased by Michael, who, after cornering her on a balcony, charges her head-on and knocks 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.
