[Plot twist spoiler] Strange things start happening in town, high school kids are the main focus. Near the end, one of the main girls realizes she doesn't remember her life outside of that town, and it's revealed that she and her family don't exist. There's a supposed calamity from her having sex with one of her classmates because of the nature of her being.

Nvm, pretty sure it's Soil
