The Babysitter (Netflix)

Cole (Judah Lewis), a 12-year-old boy who's picked on at school, is madly in love with his gorgeous neighbor, Bee (Samara Weaving), who defends him from the bullies. When she's asked to babysit him one night, they have a great time, making pizza and talking about who they would pick for their Intergalactic Dream Team. However, after he goes to bed, Bee invites some of her friends (Robbie Amell, Hana Mae Lee, Andrew Bachelor and Bella Thorne) over for a party, and when Cole sneaks downstairs to spy on them, he discovers that they're members of a satanic cult.

It turns out that Bee once made a pact with the Devil to get anything she wants. When the members of her coven discover that Cole knows about them and what they do, they have to decide whether or not to sacrifice the boy in order to keep their secret safe.
