Night. You wake suddenly.

Someone''s in your house. Is your family safe? You stumble from bed. You must investigate.

If you had a gun, would you take it? If your life was threatened, would you use it?

Richard Dane, face-to-face with an armed intruder, does. With one shot he takes a man''s life and changes his own forever.

The police say it is a clear-cut case of self-defence - the deceased is a no-account ex-con wanted by the law. No one blames Richard... except the dead man''s father who, hell-bent on revenge, sets his sights on Richard''s own four-year-old son.

As father is pitted against father, both men are inexorably drawn into dangerous territory as small-town secrets peal away to reveal a vile conspiracy that will threaten to devour them both.
