The Kelly family lives in the fictional town of Oakmoor Crossing, just before and during
Halloween. The family, consisting of father David, mother Linda, and son Sean, live a normal suburban life, but are eventually visited by a stranger who identifies herself as Vivian Machen. Both the Machens and the Kellys have a long ancestral history in Oakmoor Crossing, and Vivian reveals that one of the Kelly's ancestors hanged a supposed
warlock named Walter Machen, who raised up a pumpkinhead scarecrow, named Jack-O, from hell to take revenge on the Kellys. The Kelly ancestor ended up burying the monster in a shallow grave. But, through the antics of several teenagers, Jack-O is raised again and seeks revenge on the Kellys. ==Cast==
