Bird Box is a 2018 American post-apocalyptic horror thriller film, directed by Susanne Bier from a screenplay written by Eric Heisserer, and based on the 2014 novel of the same name by Josh Malerman. The film follows a woman, played by Sandra Bullock, as she tries to protect herself and two children from malevolent supernatural entities that make people who look at them go insane and commit suicide.

In a post-apocalyptic world, Malorie Hayes advises two young, unnamed children that they will be going downstream on a river in a rowing boat. She strictly instructs them to not remove their blindfolds, or else they will die. From this point, the film alternates between two stages of Malorie's story, separated by five years, until they conjoin: her attempt to sail the river and the events that led to it.
