The North Coast is experiencing its worst winter for thirty years. In the middle of a raging snowstorm, a solitary figure appears at a farmhouse in a remote part of Aghadowey. The elderly couple that live there let him in, but the man is freezing, incoherent... and bleeding. As they race against time trying to get his wounds treated before he dies, they learn of the events that led him to their door, and what is chasing him. Tonight, they will come face to face with something they couldn't imagine in their darkest dreams.
