Halloween

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? - IMDb
