In 1983, Michael Myers stabbed his 15 year-old sister to death. He was institutionalized and according to his doctor, Sam Loomis, is the personification of evil. On the day before Halloween 15 years later, Myers manages to escape and heads for his home town. On Halloween night, he goes on a rampage while Loomis and the local sheriff search Myers' neighborhood for him. Meanwhile Laurie Strode, a serious student who rarely goes out on dates, is babysitting a neighbor's child. Little does she know the danger she is in.
