Raised from the dead by evil wizard Walter Machen, scythe-wielding Jack-O, a pumpkin-headed Halloween Demon, returns in modern times to haunt an average American family and their babysitter, Linnea Quigley. On Halloween night, Jack-O begins hacking and slashing his way through a blood-spattered stack of drunk college students, clueless neighbors, terrified trick-or-treaters, motorcycle maniacs and a waitless cable TV installer.
