Trick 'r Treat

Opening[edit]
In the fictional Warren Valley, Ohio, Emma (Leslie Bibb) and her holiday-obsessed husband, Henry (Tahmoh Penikett), have set up numerous ghost-scarecrows for Halloween in their yard, despite the fact that Emma hates Halloween. After returning home from a Halloween party, Emma tries to blow out a jack-o'-lantern, but Henry tells her not to because it is against tradition to extinguish a jack-o'-lantern on Halloween; she blows it out anyway. While Henry is inside waiting for Emma to take down the decorations, she is murdered by an unknown assailant with a large blade-shaped pumpkin lollipop in front of the kids who were trick-or-treating, who run away in horror. Later, Henry goes outside and notices limbs hanging out of wires. Just then, one of the scarecrows lights up. He approaches it and takes down the cover, only to see Emma's severed head stuck onto the stick and wrapped in decorative lights, with her limbs chopped off and her mouth stuffed with a large lollipop, and screams in horror.
The Principal[edit]
Steven Wilkins (Dylan Baker), the town principal, spots his young neighbor Charlie (Brett Kelly) stealing candy from his yard as he returns from the store. Smiling, he places him down at his front door and talks to him about candy and stealing, carving out a jack-o'-lantern, and he gives him a candy. Charlie eats the candy, which turns out to be poisoned with cyanide, and throws up large amounts of chocolate and blood before he dies. While Wilkins is trying to take Charlie's corpse to the backyard to bury it, his doorbell rings. The trick-or-treaters, among them a small boy wearing orange footed pajamas and a burlap sack on his head, take their candy without finding out what Wilkins has done. Wilkins then buries Charlie in his backyard, along with another unknown body, and has a run-in with his neighbor, Mr. Kreeg (Brian Cox), and his dog. After finishing the burial, Wilkins sees Kreeg screaming from his window, begging for help; Wilkins disregards this and Kreeg is knocked down by an unknown assailant. Later, Wilkins arrives in his basement, where he helps his son Billy carve a "jack-o'-lantern" in their basement, which is revealed to be Charlie's severed head. The sequence ends with Billy saying "But don't forget to help me with the eyes."
The School Bus Massacre Revisited[edit]
Four kidsâ Macy Rutherford (Britt McKillip), Sam "Schrader" Hader (Jean-Luc Bilodeau), Sara Perry (Isabelle Deluce), and Chip Winslow (Alberto Ghisi), the same trick-or-treaters who earlier visited Wilkinsâmeet up with Rhonda Curran (Samm Todd), a savant, and journey to the local rock quarry where Macy tells them the local urban legend of "The Halloween School Bus Massacre". Thirty years ago, in 1977, there was a group of mentally challenged kids. Their parents were embarrassed by their conditions and saw them to be a burden to them, and as such, they were sent off to a school in another town so they would not face the townspeople's mocking. One day, on Halloween, they paid the bus driver to kill the kids so they would be freed of their burden. He drove the bus to the quarry, chained the kids to the seats, and while he was checking them, one kid managed to get free and went to the steering wheel, wanting to drive back home; however, he set the gear in forward instead of reverse and drove into the lake, drowning them all. However, the bus driver managed to get out alive &amp; was never heard from again. Some say the school bus sank so deep it couldn't be found. Others say the town didn't want the school bus to be found.
The group plays a prank on Rhonda in which they pretend to be the undead children, and chase Rhonda until she trips and knocks herself out. Macy kicks a jack-o'-lantern into the lake, whereafter the school bus children suddenly rise from the water. The undead children chase the group and manage to grab hold of the chains which Sara is wearing as part of her costume, dragging her away to be killed before she can reach the elevator. Meanwhile, Rhonda has locked herself in the elevator leading out of the quarry. Despite the others begging her to open it, she ignores them and rides it up herself as the School Bus children corner them as revenge for the prank. As Rhonda steps out of the elevator, the other kids are heard being dismembered and eaten alive. As Rhonda begins walking home, the small boy in the orange footed pajamas and burlap sack looks on at a distance.
Surprise Party[edit]
Laurie (Anna Paquin), a self-conscious 22-year-old virgin, is getting ready for a party with her older sister Danielle (Lauren Lee Smith) and their two friends Maria (Rochelle Aytes) and Janet (Moneca Delain). Annoyed by their talk about boys, she stays behind and plans to join them later. The other girls find local men to bring along with them. Later, alone on her way to the party, Laurie is attacked by a vampire dressed in black. Meanwhile, Danielle, Maria, and Janet party at a bonfire with the men they brought, with Danielle worried about Laurie. The vampire's body suddenly drops from a tree onto the party and Laurie appears. The "vampire" is revealed to be Principal Wilkins in disguise wearing fake fangs. The girls at the party, along with Laurie, suddenly transform into werewolves, removing their skin. It is revealed that Laurie's "virginity" actually signifies that she has never killed anyone before. The girls then proceed to devour their dates along with Wilkins, while the same small boy in the orange footed pajamas and burlap sack looks on.
Meet Sam[edit]
Kreeg, a Halloween-hating man, lives alone with his dog, Spite, as his only companion. Kreeg shows his disgust for Halloween by scaring away trick-or-treaters. While at his house, Kreeg is attacked by Sam (Quinn Lord), the same small boy in the orange footed pajamas who has watched over all of the events of the evening. During the struggle, Kreeg rips off the sack over Sam's head to reveal his head to be a cross between a jack-o-lantern and a human skull. Kreeg runs to his window calling for Mr. Wilkins to help him, but is tackled by Sam. Kreeg gains the upper hand when he manages to fire his shotgun at Sam, seemingly killing him, as well as shooting off one of Sam's hands in the process. As Kreeg dials 9-1-1, Sam re-attaches his hand and rises. Sam then attacks him again, stabbing at him with a large pumpkin lollipop out of which he has taken a bite, rendering it sharp. Sam finds that the lollipop has lodged itself into a piece of chocolate from which Kreeg had earlier taken a bite. Sam takes the lollipop wedged into the chocolate and walks away, now satisfied that Kreeg has fulfilled a tradition of Halloween. Meanwhile, pictures burning slowly in a nearby fireplace show a class photo of the masked children from the "School Bus Massacre" and the bus driver, who is revealed to be Kreeg.
Conclusion[edit]
Bandaged and bruised from his encounter with Sam, Kreeg answers his door to give candy to trick-or-treaters. While on his porch, he spots Sam walking over to Emma and Henry's house just after she blows out the jack-o'-lantern, revealing himself as Emma's killer in order to punish her for not following Halloween's rules. A traumatized Rhonda walks across the street and is almost hit by the laughing, human-form werewolf girls in their car, on their way back from the surprise party. Billy is sitting on his porch handing out candy, unaware that his father is now dead. Kreeg then walks back inside when there is another knock at the door. He opens the door to find the kids from the School Bus Massacre standing there with their bags outstretched, saying, "Trick 'r Treat", and, suddenly recognizing them, stares in shock. A series of comic strip panels shows Kreeg being murdered and dismembered by them, the kids had gotten their revenge.
