Brynn (Kaitlyn Dever) lives in a big house just outside their small village. All alone, with nothing really to do besides sew and build a miniature model of their town, she spends her time at the grave of her mother. She tries to drive around town and greet the townsfolk with a smile and a wave, but for some reason they avoid making any interactions with her.
One night, she wakes up to the sound of something breaking into her home. Curious about the clattering and the chirping, Brynn tries to take a good look at her intruder. She then discovered something shocking: her housebreaker isn’t human at all. It’s an alien.
