Set in Belfast during the 1975 ceasefire, the film shows us a war fought not by soldiers but by rival gangs. The factions police themselves and leave the police out. Neighborhoods are partitioned off with barricades. One of the Protestants, a member of the 'Shankill Road Loyalists,' declares their purpose is to actively drive the Catholics out or 'South' as he puts it. He also claims that it's 'nothing personal' to a Catholic he's beating in the street. It's tribal warfare. They instruct the next generation to carry on the prejudice. But, a strange thing happens when a Catholic found on the wrong side of the barricade turns out to be an old friend before the troubles. We know that loyalty is important, the question is to whom.
