For Carlos, Maya, Ben, and Chloe, a school residential in the remote Welsh valleys was meant to be a chance to escape their troubles. But when a night-time treasure hunt in the dense, ancient woods goes wrong, they find themselves deliberately separated from their group. Branded the 'naughty kids', their disappearance is met with apathy, but the reality is far more terrifying. Unbeknownst to them, they've stumbled into a sinister game orchestrated by an unseen tormentor, designed to exploit their deepest fears and volatile emotions. Trapped in a disused activity centre, surrounded by disorienting forests and unsettling local legends, the friends must navigate a series of escalating psychological torments. Carlos's impulsive bravery clashes with Maya's rising anxiety, Ben's artistic sensitivity offers cryptic clues, and Chloe's usual humour crumbles under the weight of genuine fear. As suspicion breeds within the group and past traumas resurface, they must confront not only their external captor but also their own internal demons. To survive, they'll need to dismantle their usual defences, learn to trust each other, and find the strength to regulate their own behaviour before the game consumes them entirely, with a chilling cliffhanger leaving their fate uncertain.
