Christine Springfield (Cara Delevigne), 17, studies in a school in the middle of nowhere. Like, literally, it's surrounded by miles and miles of grassy plains.

Andy Peterson (Thomas Brodie-Sangster), 18, attends the same school Christine does. Her childhood best friend up until now. Haven't had a girlfriend since birth.
