Sergeant 'Hex' Rexford is the detective who caught the infamous serial killer Dr. Witcherton. Now, with a series of gruesome murders unfolding inside Coast Sanctuary - a hospital for the criminally insane - Witcherton claims to know who's behind them. Hex takes the case, determined to uncover the truth, even as his own body is failing him.

Beth Thompson is desperate to keep her children safe. Her violent ex is stalking her, her son's behaviour is growing strange, and his beloved teddy bear, Theo, might be more than just a toy. When an elderly woman offers Beth a remote cottage, it feels like a chance to breathe - but safety is an illusion.

Meanwhile, true crime podcasters Eve and Zane are chasing the story of the murders. But as Eve edges closer to the truth, the danger closes in.

As past and present collide, and the body count rises, the threads connecting them all begin to tighten - and something terrifying is watching from the dark.
