A young man lies bleeding in the street. It's Glasgow and it's May - the marching season. The Orange Walks have begun. Graham doesn't want to be involved. He just wants to play football with his mate, Joe. But then he witnesses a shocking moment of violence and suddenly he is involved. With Catholics and with Protestants; with a young Muslim asylum-seeker and his girlfriend. A gripping tale of two boys who must find their own answers - and their own way forward - in a world divided by differences.
