In the first days of World War I four soldiers, left behind as the British army retreated through northern France under the first German onslaught, found themselves trapped on the wrong side of the Western Front, in a tiny village called Villeret. Just a few miles from the Somme, the village would be permanently inundated with German troops for the next four years, yet the villagers conspired to feed, clothe and protect the fugitives under the very noses of the invaders, absorbing the Englishmen into their homes and lives until they could pass for Picardy peasants.
