Bound, gagged and blindfolded, several wayward teens are grabbed in the middle of the night and taken to Redback, a youth behaviour modification camp, deep in the Australian bush. They're completely cut off from the rest of the world; isolated and tested in the unforgiving environment. Whispers circulate through the camp that a few years earlier a girl was found hanged in one of the cabins, the circumstances of her death, mysterious. Was it suicide, orsomething more sinister. Only the dead girl knows the truth, and the dead don't talk... unless they find someone who can hear them...
