At Challow Hall Children's Home, a group of four children - abandoned, abused, neglected - had been drawn to each other early on, bonded by their shared experience. When they first start acting out parts from Lord of the Flies, it is an innocent, childish game. But then one of their support workers joins in - a woman in a position of responsibility and trust - and the game gradually takes on a more sinister edge.
Each member of group has their own agenda, their own reasons for wanting vengeance. Together, they will select their victims and act out their darkest, most primitive urges in a "game" that will have horrifying consequences.
