Plot
Twelve-year-old Cole Johnson is bullied by his neighbor Jeremy, but his babysitter Bee stands up for him and scares Jeremy off. The following day, when his parents go out for an overnight stay at a hotel, Bee and Cole spend quality time together until he has to go to bed.

Cole is encouraged by a text from his other neighbor and best friend Melanie to go see what Bee gets up to after he goes to sleep. He sees Bee and several of her high school friends (Max, John, Allison, Sonya, and Samuel) playing a game of truth or dare formatted as a game of spin the bottle. However, as Bee kisses Samuel on a dare, she pulls two daggers from behind her back and stabs him in the skull. The others collect Samuel's blood, revealing themselves to be members of a demonic cult. Cole hurries to his room where he calls 911, puts on his shoes, and finds his pocket knife. He pretends to be asleep as Bee and the cult members enter his room to draw a sample of his blood. After they leave, he tries to escape out the window but Bee stays in the room, and Cole passes out from the exhaustion and loss of blood.

Bee and her cult question Cole, while fending off his questions by saying it was a science project. When the cops arrive, Max throws a fire poker through the eye of one of them, but the cop accidentally shoots Allison in the chest, while Bee and Max kill the other cop by slicing his throat. Max tears out the fire poker from the cop's eye, killing him. Bee forces Cole to give them the police code to call off the other cops. While Allison complains about being shot, Cole rushes up the stairs; John pursues him, but is pushed over the banister, landing on a trophy that impales his neck.

Cole escapes out his bedroom window and hides in the crawlspace under his house. Although Sonya finds him, he traps her in the basement and then ignites a firework rocket and bug spray, blowing her up. After showing appreciation for Cole's ingenuity, Max chases Cole up a tree house; he is killed when he falls and is hanged by the rope swing. Cole escapes to Melanie's house, but Bee follows him. While hiding in a room, Cole apologizes to Melanie for dragging her into this situation and assures her that he is going to take care of things. He asks Melanie to call the police, then she kisses Cole before he leaves.

Cole returns to his house to find Allison, who tries to kill Cole with a kitchen knife; she instead has her head blown off with a shotgun by Bee. Bee explains to Cole that when she was young, she made a deal with the Devil to get whatever she wanted by sacrificing innocent people and spilling their blood on an ancient book while reciting its verses. Although she wants him to join her, Cole refuses and burns the spell book. He rushes to Melanie's house to take her dad's car, and drives it to his house while Bee tries to rescue the book from flames in the living room. After crashing the car into her, they have one last emotional farewell before Cole climbs out of the wreckage. As the police and emergency crew arrive, Cole tells his parents that he no longer needs a babysitter.

Later, a firefighter going through Cole's house is attacked by Bee, who survived her wounds.
