...It's a nice quiet evening at Betty's house. She is relaxing in her favorite T-shirt cutting out a pizza coupon and waiting for dinner to arrive while Brett is sitting at the computer. He is googling the latest wind currents when all of a sudden Pumpkinhead III smashes through the window. Before Brett can even leave the computer, he notices his guts all over the keyboard. PHIII begins rushing full force toward Betty. He smashes the aquarium she is standing in front of and it explodes all over them. Betty bolts out the door. She reaches the end of the driveway and notices a car driving slowly towards her. It's Cal, the delivery guy. Betty jumps in the car. "WHOA LADY!" yells Cal. "DRIVE! HE'S COMING!" she screams. Before Cal can even ask who, Pumpkinhead III jumps on the hood of the car. Cal slams on the gas and peels out of the neighborhood leaving Pumpkinhead III in his dust. PHIII reaches down on the ground and picks up a pizza hut coupon.
"What the fuck was that?" asks Cal.
"I don't know, but I need to find out. Take me to the Internet." says Betty.
"Ok, but I have to go back to the store first and close out."
"No, there's no time. We're going to die if we waste another second."
"Oh God, Patty's going to smoke my nuts."
The inside of the Pizza Hut is deadly quiet except for the faint sound of "Trenchtown Rock" coming from the freezer. Patty is in the freezer riding the Sisco delivery guy when she hears the front door chime. "It's about goddamn time that motherfucker made it back," Patty says in-between pulls from her spliff. (We now have a point-of-view shot of someone walking through the store) The camera stops in front of one of the pizzas and lovingly examines it before a yell from the freezer interrupts its concentration. "START DOING THE DISHES DOUCHEBAG. I AIN'T GOING TO PAY YOU TO SIT AROUND AND WHACK OFF ALL NIGHT." The camera begins moving towards the freezer. The freezer door slowly opens and Patty is smoking and fucking the Sisco delivery guy. "We're Closed...Who the fuck are you?", Patty hollers as the freezer door opens and she sees Pumpkinhead III standing there. She picks up one of the pepperoni rolls on the floor and throws it at him. Pumpkinhead III catches it, eats it and then slaughters Patty and the delivery guy.
Meanwhile, Betty and Cal are at a nearby Internet cafe. Cal googles pumpkin-head and a bunch of smashing pumpkins fan sites come up. "NO, Let me do it. You have to put Pumpkinhead in quotes." Betty googles pumpkinhead and finds some sites about the pumpkinhead demons. She learns that this is Pumpkinhead III and also finds out information about his hiding places, strengths and weaknesses. They learn that past pumpkinheads usual hide out in abandon warehouses, so Betty pulls up a list of nearby warehouses. At first Cal doesn't want to go looking for Pumpkinhead III, but he doesn't want to puss out on Betty. His dick knows what's right, so he decides to tag along.
They arrive at the third warehouse on their list and notice some empty pizza boxes on the floor. Pumpkinhead III is passed out on a box which has been set-up as a makeshift desk. He has been googling some cool shit on the computer, computer stolen from Rudy, and drinking cough syrup that he took from a pharmacy. The cough syrup is causing him to have crazy dreams, like the google logo jumping off the screen and crap like that, so he doesn't think that it is weird when he awakens and sees Betty laying on an old mattress set-up next to the toilet. Pumpkinhead III, still woozy from the cough syrup, gets up and walks over to Betty. She signals him to sit down by her, but her aggressiveness frightens him. He decides to sit on the toilet next to the bed. Betty slowly leans closer to Pumpkinhead III, but before she can get too close Cal runs out from behind the bedroom wall. Cal pulls out a knife and cuts Pumpkinhead III wide open, right through the middle of his body. Pumpkinhead III's guts fall into the toilet and Cal flushes them, along with the rest of PHIII's body.
"You did it," Betty shouts as she throws her arms around Cal.
"Alright! Pumpkinhead III is dead." They relax. "You wanna smoke this joint?", Cal asks as he reaches for the lighter in his pocket.
Cut to:
A neighborhood street at night. It is halloween. The sidewalks are filled with kids trick or treating. All of sudden the manhole cover in the middle of the street explodes and a huge stream of blood goes flying into the sky. Everyone stands frozen for a second and then looks up and sees a demon with a pumpkin for a head flying in the night. Pumpkinhead III lets out a blood curdling scream and then begins a nosedive straight to the street. PHIII is spitting fire everywhere and everyone begins running all over the place. Pumpkinhead III's rampage has begun. In just a couple of minutes the street is littered with bodies, empty candy wrappers and blood. Pumpkinhead III is satisfying his every pleasure and it seems that there is no end in sight.
Betty takes a slow pull from the joint and then gently exhales. "I thought for sure he was going to kill me." Cal takes the joint from her, "He would have had to kill me first." He leans in and is about to kiss her when her cellphone starts ringing. It's the cameraman from her station. He is standing outside the news van in the midst of the rampage.
"BETTY, WHERE THE HELL ARE YOU? I'M IN THE LAKEVIEW NEIGHBORHOOD AND IT LOOKS LIKE GOD HAS PUKED DEAD PEOPLE ALL OVER THE WHOLE WORLD. SOME KIND OF FLYING FREAK IS KILLING EVERYTHING. GET DOWN HERE NOW BEFORE YOU MISS THE BIGGEST STORY OF YOUR LIFE."
Betty hangs up the phone, "We gotta go." Cal offers Betty the keys to his car. She grabs the keys out of his hand, the joint out of his mouth and then runs out the door. Cal reluctantly runs after her.
They arrive at the scene of Pumpkinhead III's massacre; Cal steps out the car and immediately starts throwing up. Betty begins talking to the cameraman about what has been happening, but is interrupted when PHIII comes swooping in. Pumpkinhead III annihilates the cameraman and then knocks Cal to the ground. After a short fight Cal pins PHIII to the ground. He is ready to cut PHIII's head off with his knife, but is suddenly kicked to the ground. It is the brother of the kid whose death was avenged by Pumpkinhead I. The brother explains that he is here to help Pumpkinhead III because PHIII's grandfather avenged his brother's death. The brother pistol-whips Cal, knocking him out. Betty jumps on the brother's back and gets thrown to the ground. PHIII flys into the sky and the brother aims his gun at Betty and Cal. Betty says some shit about how PHIII is a demon without a heart, but the brother is crying that his family owes it to PHIII.
Then...this kid on a bike, just like his brother in part one, rides by holding a trick or treat bag. The brother turns and watches him ride by, but PHIII comes swooping down. He takes the kid's candy bag, throwing him off the bike and causing him to hit the street hard and die. The brother runs over and picks up the kid's lifeless body, "NOOOOOO!, COME HERE YOU DEMON BASTARD! I'VE GOT SOME CANDY FOR YOU!" PHIII comes swooping down AGAIN. He torches a big circle of fire around the news van, the brother, Betty, and Cal (still knocked-the-fuck-out). PHIII and the brother fight, but the brother dies quickly and gruesomely. During the fight, Betty gets a bottle of hairspray out of her vanity bag in the news van. She runs up behind PHIII and when he turns around she throws the bottle of hairspray at him. It goes right into his mouth and exactly one second later his fucking head EXPLODES! The explosion wakes Cal up. Betty grabs his body and pulls him out of the circle of fire right before the van explodes.
