Halloween: Resurrection

Three years after the murders at Hillcrest Academy,[a] a guilt-ridden Laurie Strode is institutionalized in Grace Andersen Sanitarium. It is revealed that the person she previously decapitated, whom she believed to be Michael Myers, was in fact a paramedic that Michael had switched clothes with and rendered mute. Anticipating her brother's inevitable return, Laurie sets a trap on the sanitarium's roof.
Michael appears and chases Laurie to the rooftop, where her trap works and temporarily incapacitates Michael. However, Laurie's fears of killing the wrong person again get the better of her. When she attempts to remove his mask to confirm his identity, Michael stabs and throws her off the rooftop to her death. He gives his knife to a mental patient as a souvenir, framing him for the murder of Laurie and two security guards.
A year later, college students Sara Moyer, Bill Woodlake, Donna Chang, Jen Danzig, Jim Morgan and Rudy Grimes win a competition to appear on an Internet reality show called Dangertainment, directed by Freddie Harris and Nora Winston. The students have to spend a night in Michael's abandoned childhood house in order to figure out what led him to kill. However, while setting up cameras throughout the house in preparation for the show, cameraman Charlie is killed by Michael, who has returned to Haddonfield. On Halloween night, equipped with head cameras, Sara, Bill, Donna, Jen, Jim, and Rudy enter the house and separate into three groups to search for clues. While Sara messages the others, Myles "Deckard" Barton watches the live broadcast during a party. During the search, Michael suddenly appears and kills Bill.
Donna and Jim discover a wall filled with fake corpses and realize that the show is a setup, before the former is killed by Michael. At the party, Deckard and other partygoers witness the murder; only Deckard realizes that it was real. Meanwhile, Freddie enters the house dressed as Michael in order to scare the competitors. He is followed by the real Michael, whom he mistakes for Charlie and shoos out of the house towards the garage where Nora is. When Rudy, Sara, and Jim find Freddie in the Michael costume, he reveals the scheme to them and begs them to cooperate, telling them that they will all be paid well if the show works out. After Freddie leaves, the trio decides to gather up the rest and leave. Jen discovers Bill's corpse, and Michael decapitates her in front of Rudy, Sara, and Jim, who soon realize that it isn't Freddie. Michael proceeds to kill Jim and Rudy before chasing Sara upstairs.
Locking herself in a bedroom, Sara begs Deckard to help her. As the other partygoers realize that all the murders are real, Deckard begins to message Sara Michael's locations to help her avoid him. Sara runs into Freddie just as Michael finds them and stabs the latter. Sara runs into the tunnels and finds an exit leading to the garage, where she discovers Nora's body[nb 1]. Michael again arrives and attacks Sara, but a still-living Freddie finds them and fights Michael as an electrical fire starts in the garage. After electrocuting Michael, Freddie carries Sara to safety, leaving Michael to die in the burning garage. Later, Freddie and Sara are interviewed by the local news, during which Sara thanks Deckard for saving her life and Freddie assaults the reporter. Meanwhile, Michael is presumed dead and his body is taken to the morgue. However, as the coroner prepares to examine his body, Michael suddenly awakens.
In an alternate ending, Sara requests to look at the bodybag seemingly containing Michael's corpse. Upon opening, Michael awakens and chokes Freddie until Sara kills Michael by stabbing him in the face with an axe.
