1914. A boy enrols in the army, hoping to find peace in the great adventure of war. Handed a rifle, he discovers the grim reality: grey days distinguished only by the ever-present spectre of death. In the midst of horror, he finds close friendships, love and companionship. In an unexpected act of courage, he changes the course of history, bringing German and Brits to put down their weapons for a celebration of peace. In 1933, a father and son set out for Flanders. The former soldier carries more of the war with him than his maimed left hand. The British man he met in the forest of Ypres is a memory passed down from father to son, a story of friendship across enemy lines, forged by one uniting belief: the need for peace.
