Cregger explains why he had to drop a lot of the film’s jokes, while Brolin reveals why he initially hesitated when approached for the film.

The event at the movie's heart is the disappearance of 17 third-graders from a single class in the middle of the night in the leafy town of Maybrook, Illinois. Ring cameras catch them opening their front doors and rushing out, not to be seen again. Only one child from the class showed up the next day at school.
