Teen Kathrin Fletcher is your everyday girl. And of course, she would rather be with her friends on the last day of school. That's just what she does. The group, consisting of Mia, Xander, Felix, Nicole, Brayden, Zach, Annabelle, and Julie, set out to Mia's hidden summer house. It starts off as an amazing vacation, but for the group of light hearted teens, it goes from vacation, to living hell. Kathrin is falls unconscious, Mia goes missing, and as they are picked off one by one, like popcorn from a bag, they all begin to wonder if the end... is closer than they thought.
