Natalie isn't allowed out tonight, even though her friends on the other side of town are … on Halloween, trick or treating and eventually going to the biggest party in town. Upset and pissed off at her parents, she storms up to her bedroom to do what most teenagers do … play on their phone. Headphones on to ease the silence, she receives various texts, Facebook updates and Snapchats on how creatively the houses are decorated and how high the candy piles are stacking up.
Not only that, but her crush is amongst the costumed team of five hitting the streets in the large town of Derwan. It's getting late. Natalie takes an unintended nap, but when she wakes up to various eerie Snapchats from Sarah, her closest friend, of the others being grotesquely tortured, terror sets in.
Is it worth the risk to sneak out to find her friends and get help before it's too late?
