Horror directed by Caradog W. James and starring Katee Sackhoff, Lucy Boynton and Javier Botet. When Chloe (Boynton) and her boyfriend Danny (Jordan Bolger) decide to knock twice on the door of the supposed witch Mary Aminov (Ania Marson), they treat it as a silly joke. But when Danny disappears without a trace Chloe realises too late that the urban myth may have more truth to it than she anticipated. Detective Boardman (Nick Moran) is charged with investigating the disappearance and Chloe seeks shelter with her estranged mother (Sackhoff). But a darkness follows her every step.
