Christmas Eve, 1914. Young Private O'Malley, staring over the crest of a trench deep in the heart of France, regales his comrades with nostalgic images of home as he describes his parents' Christmas preparations back in Brighton. But when a curious group of German soldiers singing Silent Night step out of the trenches and approach the British line of defense, O'Malley and his mates have to decide if there's enough Christmas magic in the air which would allow the weary soldiers a brief respite from the ravages of war on the holiest of nights.
