Let Us Prey

A menacing stranger ( Liam Cunningham) turns up in the middle of the night at a police station in a remote Scottish town. After being placed in a holding cell, it's not long before the stranger initiates a terrifying chain reaction of madness and violence amongst the inmates and then the police officers, leaving one of the few unaffected, a newly hired female officer (Pollyanna McIntosh), with her back to the wall, not knowing who she can trust, fighting for her life.
