Having been institutionalized at the age of six after murdering his sister, Michael Myers, now an adult, has escaped. Certain that Michael will kill again, Dr. Loomis (Donald Pleasence), the psychiatrist under whose care Michael has been, makes it his mission to find Michael before he does. In Michael’s hometown, Laurie Strode (Jamie Lee Curtis) is babysitting Tommy Doyle (Brian Andrews) on Halloween night. Her good friend Lynda is also babysitting across the street, but being more interested in seeing her boyfriend than hanging out with a little girl, she sends the girl over to the Doyle’s so that she can pick up her boyfriend. Not long after, Tommy claims to have seen the Bogeyman while looking out the window. Laurie, not pleased with the night’s events, eventually heads across the street to find out what’s going on. Little does she know, her friends are in grave danger, and she may be next.
