Plot

Dick Harbinger is a police officer obsessed with stopping history from repeating itself. Thirteen years ago, a man wearing a pumpkinhead and driving a lawnmower murdered several children. The night is Halloween and everyone is a suspect. The school janitor, Zeke, is brought in for questioning. Throughout the film, when the word "geek" is used, he reappears and corrects the speaker saying, "it's Zeeeeke". The father of the family is too obvious a suspect and is questioned by police. He is usually caught by his daughter Mary, trying to creep into the bathroom when she is showering, or peering in her window whilst she is sleeping. His daughter catches him and screams and always says the same line, "Damn it Daddy, what are you doing?" Kennedy always replies, "I'm just, erm, mowing the lawn." The daughter's reply is always the same, "sure Daddy, that's what you always say." Mary's friend Rosie is dating Tony "the Schlong" Schlongini, who is the coolest kid in school. He along with many others get killed by Mr. Pumpkinhead which is played by detective.
