Game of Thrones’ Liam Cunningham plays the menacingly taciturn stranger who fetches up one night in the cells of a backwater Scottish town in stylishly shot but very gruesome horror thriller Let Us Prey.

He seems to be a demonic angel of retribution, able to see into the hearts of his fellow cellmates and the cops. And everyone present – save for Pollyanna McIntosh’s haunted rookie cop – harbours a very dirty secret or two.

With the station clock ticking down to midnight, first-time director Brian O’Malley turns the screw of suspense with fiendish relish and ensures the wicked meet very bloody ends. Gorehounds will lap this up, but fainthearts should steer clear.

Certificate 18. Runtime 88 mins. Director Brian O’Malley.

Let Us Prey is available on Digital & DVD from Kaleidoscope Home Entertainment.
