Terrifier 4

In Bayleen Bay, an ice cream truck run by a mysterious, silent man arrives and quickly becomes popular amongst the local children. Lactose-intolerant Jared Mayfair avoids eating the treats and is unsettled by the Ice Cream Man, whom he sees following him as he cycles home. He also notices that the children who have eaten the treats are in a trance and watching videos depicting the cartoon character on the truck. That night, the truck drives through the neighborhood, awakening the children who have eaten the treats. Possessed, they gruesomely murder their parents. The next day, Jared and classmates Tommy and Mia, who have also not eaten the treats, notice strange behavior in their peers. The truck arrives at the school, and the children begin killing their teachers and any other adults in town while force-feeding treats to any non-possessed children. Jared, Tommy, and Mia evade their murderous classmates and barricade themselves in the school. Meanwhile, Jared's teenage sister Lizzie eats the ice cream intended for Jared and becomes paralyzed but makes herself vomit up the treat. When Jared calls for help, Lizzie instructs him to meet her at the local church before some neighborhood children attack the house. Lizzie's ex-boyfriend Chris saves her, and both drive to the church. As Bayleen Bay descends into chaos, Jared, Tommy, and Mia escape from the school and seek refuge in the church's basement. They discover a giant walk-in freezer filled with the Ice Cream Man's treats and find the local priest hiding there. The priest explains that the Ice Cream Man is Jonathan Smiley, a once kind-hearted man who visited Bayleen Bay decades ago and was unjustly blamed for hurting local children to cover up the actions of the town's predatory priests. Jared's grandfather, an influential lawyer, ran the case against Jonathan, and the children were pressured to lie, which led to Jonathan being convicted. While in prison, Jonathan had been visited by a necromancer who promised him revenge on the town in exchange for his soul. To stop Jonathan, the kids must kill the necromancer and the siren accompanying him in his unmarked grave. When Jonathan arrives at the freezer, the priest sacrifices himself to give the kids enough time to run. Jared, Tommy, and Mia reunite with Lizzie and Chris and convince them to drive to the cemetery to find the necromancer's grave. As they dig up the bodies, the children kill Chris before force-feeding treats to Mia and Tommy, possessing them. Cornered by Jonathan, Jared and Lizzie stab the bodies in the grave, but realize too late that they have killed their own parents. The priest is revealed to be the necromancer, having tricked them to help finish the job for Jonathan. While the guilt-ridden and traumatized Jared and Lizzie are left surrounded by the carnage, Jonathan leaves the now-decimated Bayleen Bay with the possessed children following him, his revenge complete as he goes to terrorize the next town.
