An Irish woman with magical powers and her teenage son go into hiding on a Scottish council estate, but are pursued by a killer with similar abilities sent by their own people. As the boy falls for a local girl and risks breaking cover, a murderous creature roams the streets with some connection to either hunter or hunted. Horror, starring James Nesbitt and Kate Dickie.

When Mary and her teenage son, Fergal, move to yet another new home, it soon becomes clear they live their lives on the run, hiding from someone or something, terrified of being found. Their hunter, Cathal, soon picks up the trail. Intent on tracking Mary and Fergal, he will go to any lengths to succeed in his quest, often using dark arts to aid him. Mary’s only defence is to use an ancient form of her own magic to protect her only son. When local residents begin to be brutally murdered by an unknown life force, the sense of fear escalates. Is Cathal the beast responsible for the killing? Or is it the beast that he is trying to destroy?
