It's New Zealand, 1914, and the biggest war the world has known has just broken out in Europe. William eagerly enlists for the army but his younger brother, Edmund, is a conscientious objector and refuses to fight. While William trains to be a soldier, Edmund is arrested. Both brothers will end up on the bloody battlefields of France, but their journeys there are very different. And what they experience at the front line will challenge the beliefs that led them there.
