The residents of Haddonfield don't know it yet... but death is coming to their small sleepy town. Sixteen years ago, a ten year old boy called Michael Myers brutally kills his step father, his elder sister and her boyfriend. Sixteen years later, he escapes from the mental institution and makes his way back to his hometown intent on a murderous rampage pursued by Dr Sam Loomis who is Michael's doctor and the only one who knows Michael's true evil. Elsewhere a shy teenager by the name of Laurie Strode is babysitting on the night Michael comes home... is it pure coincidence that she and her friends are being stalked by him?

On Halloween 1963, Haddenfield, 10-year-old Michael Myers, estranged and mentally unstable, is imprisoned in Smith's Grove Sanitarium under the care of Dr. Sam Loomis for the murders of his mother's boyfriend, his older sister, and her boyfriend. Now, 16 years later, he escapes and now in search of his baby sister Laurie and Dr. Loomis must warn the residents of Haddenfield and get to Laurie before Michael does.
