Set against the backdrop of a prestigious private school, a foreboding forest, and the quiet sprawl of Bristol, this chilling mystery drama focuses on local headmaster Michael Polly, who becomes the prime suspect in his wife Sarah’s disappearance - an upstanding member of the community, Michael is inscrutable and likes order and precision in his working life... until, that is, he encounters super-bright and gutsy detective Annie Cassidy, and a compulsive game of cat and mouse begins as she chips away at his veneer in search of the truth. With tension in the air, yet Michael not displaying any emotion, Annie’s suspicions are heightened the more she investigates. Something in her gut tells her all is not what it seems - could he be capable of murder, and if so, why? With Sarah and Michael’s daughter Alana, a teacher at the school, making their involvement a real family affair, beneath the surface of the mystery lies a deeper exploration of trauma, trust, and the legacy of elite institutions.
