If you recall the end of part 4, Michael Myers (Don Shanks) was filled fill of lead and dumped down a mine shaft and dynamited for good measure. Little Jamie (Danielle Harris) seemed wiling to take up the family business though, as she stabbed her adaptive mother while Dr. Loomis (Donald Pleasence) screamed in horror.
Turns out Michael's just fine. Apparently a chest of buckshot just requires a long nap, as Michael is up and ready to go just a year later. Murdering the old man who sheltered him, Michael makes his way home.
Jamie, meanwhile, isn't doing so good. She's been mute and hospitalized since she attacked her mother, and what's more she seems to be seeing things through Michael's eyes. Dr. Loomis feels this might be important, so he tries pleading with Sheriff Meeker (Beau Starr) to listen to him. Meeker is less than convinced.
Michael hits town and begins the killing in earnest, taking out Jamie's older sister Rachel (Ellie Connell) and Mike (Jonathan Chapin), boyfriend of Rachel's best friend Tina (Wendy Kaplan). Tina, unaware of her newly single status, goes to a Halloween party with the rest of friends. Pity that Michael is waiting...
Jamie, regaining the ability to speak, tries to warn Dr. Loomis, who in turn warns the police. It does little good for most of the characters, but Loomis gets Jamie to draw Michael to the old Myers home, where the doctor is waiting with a 2X4. Will it be enough?
Supposedly shot without a script and it shows. Rarely has a film that doesn't star Adam Sandler annoy me this much. Characters we like die no matter what, plus Michael seems to less human and more machine; plus the end, well, I thought Friday the 13th had a copout ending, but this one is the new standard.
