Halloween

On Halloween in Haddonfield, Illinois, having already shown signs of psychopathic tendencies, ten-year-old Michael Myers (Daeg Faerch) murders a school bully (Daryl Sabara). Later that evening, he murders his older sister Judith (Hanna R. Hall), his motherâs 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 stateâs history, Michael is found guilty of first-degree murder and sent to Smith's Grove Sanitarium under the care of child psychologist Dr. Samuel Loomis (Malcolm McDowell).
Michael initially cooperates with Dr. Loomis, claiming no memory of the murders. His mother, Deborah (Sheri Moon Zombie), visits him regularly. Over the following year, Michael becomes fixated on his papier-mÃ¢chÃ© 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. Loomis, having continued to treat Michael over the years, attempts to move on with his life and closes Michael's case. Later, while being prepared for transfer to maximum security, Michael escapes Smith's Grove, killing the sanitarium employees and a truck driver for his clothes, and makes his way back to Haddonfield. On Halloween, Michael arrives at his now abandoned childhood home, where he 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 goes to babysit Tommy Doyle (Skyler Gisondo). Meanwhile, Lynda meets with her boyfriend Bob Simms (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). Loomis, having been alerted of Michael's escape, comes to Haddonfield looking for Michael. 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 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. During sex, Michael kills Paul and attacks Annie. Bringing Lindsey home, Laurie finds Annie on the floor, badly hurt but still 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 beloved younger sister, presenting a picture of the two 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, but she is chased by Michael, who, after cornering her on a balcony, charges her head-on, knocking both of them over the railing. Laurie comes to on top of an unconscious 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.
